 Titus 2:11-14
 11 For the grace of God that bringeth salvation hath appeared to all men,
 12 Teaching us that, denying ungodliness and worldly lusts, we should live soberly, righteously, and godly, in this present world;
 13 Looking for that blessed hope, and the glorious appearing of the great God and our Saviour Jesus Christ;
 14 Who gave himself for us, that he might redeem us from all iniquity, and purify unto himself a peculiar people, zealous of good works.
 
 We will begin with the Barclay commentary.
 
 THE MORAL POWER OF THE INCARNATION
 
 First the verses paraphrased:
 
 Titus 2:11–14
 For the grace of God, which brings salvation to all men, has appeared, schooling us to renounce godlessness and worldly desires for forbidden things, and to live in this world prudently, justly and reverently, because we expectantly await the realization of our blessed hope – I mean the glorious appearing of our great God and Saviour Jesus Christ, who gave himself for us to redeem us from the power of all lawlessness, and to purify us as a special people for himself, a people eager for all fine works.
 
 THERE are few passages in the New Testament which so vividly set out the moral power of the incarnation as this does. Its whole stress is the miracle of moral change which Jesus Christ can work.
 
 This miracle is repeatedly expressed here in the most interesting and significant way. Isaiah once exhorted his people: ‘Cease to do evil, learn to do good’ (Isaiah 1:16–17). First, there is the negative side of goodness, the giving up of that which is evil and the liberation from that which is low; second, there is its positive side, the acquisition of the shining virtues which mark the Christian life.
 
 First, there is the renunciation of all godlessness and worldly desires. What did Paul mean by worldly desires? The early Church father, John Chrysostom, said that worldly things are things which do not pass over with us into [the Kingdom] but are dissolved together with this present world. People are very short-sighted if they set their hearts and expend all their energies on things which they must leave behind when they quit this world. But an even simpler interpretation of worldly desires is that they are for things we could not show to God. It is only Christ who can make not only our outward life but also our inward heart fit for God to see.
 
 That was the negative side of the moral power of the incarnation; now comes the positive side. Jesus Christ makes us able to live with the prudence which has everything under perfect control, and which allows no passion or desire more than its proper place; with the justice which enables us to give both to God and to our neighbors that which is their due; with the reverence which makes us live in the awareness that this world is nothing other than the temple of God.
 
 The dynamic of this new life is the expectation of the coming of Jesus Christ. When a royal visit is expected, everything is cleaned and decorated and made fit for royal eyes to see. Christians are men and women who are always prepared for the coming of the King of Kings.
 
 Finally, Paul goes on to sum up what Jesus Christ has done, and once again he does it first negatively and then positively.
 
 Jesus has redeemed us from the power of lawlessness, that power which makes us sin.
 
 Jesus can purify us until we are fit to be the special people of God. The word we have translated as special (periousios) is interesting. It means reserved for, and it was used for that part of the spoils of a battle or a campaign which the king who had conquered set apart especially for himself. Through the work of Jesus Christ, Christians become fit to be the special possessions of God.
 
 The moral power of the incarnation is a tremendous thought. Christ not only liberated us from the penalty of past sin; he can enable us to live the perfect life within this world of space and time; and he can so cleanse us that we become fit in the life to come to be the special possession of God. ~Barclay Commentary
 
 Now to the other commentaries. We begin with the general and go to the specific.
 
 This from the Matthew Henry Main. This commentary covers verses 11-14. I will give you the part of this commentary which discusses the meaning of verse 13
 
 (3.) To look for the glories of another world, to which a sober, righteous, and godly life in this is preparative: Looking for that blessed hope, and the glorious appearing of the great God and our Saviour Jesus Christ. Hope, by a metonymy [a figure of speech that consists of the use of the name of one object or concept for that of another to which it is related], is put for the thing hoped for, namely, [the Kingdom] and the felicities [state of being happy] thereof, called emphatically that hope, because it is the great thing we look and long and wait for; and a blessed hope, because, when attained, we shall be completely happy for ever.

And the glorious appearing of the great God and our Saviour Jesus Christ. This denotes both the time of the accomplishing of our hope and the sureness and greatness of it: it will be at the second appearing of Christ, when he shall come in his own glory, and in his Father's, and of the holy angels, Luke 9:26. His own glory which he had before the world was; and his Father's, being the express image of his person, and as God - man, his delegated ruler and Judge; and of the holy angels, as his ministers and glorious attendants. His first coming was in meanness, to satisfy justice and purchase happiness; his second will be in majesty, to bestow and instate his people in it. Christ was once offered to bear the sins of many; and unto those that look for him will he appear the second time, without sin, unto salvation, Hebrews 9:28. The great God and our Saviour (or even our Saviour) Jesus Christ; for they are not two subjects, but one only, as appears by the single article, tou megalou Theou kai Sōtēros, not kai tou Sōtēros, and so is kai rendered 1 Corinthians 15:24, When he shall have delivered up the kingdom to God, even the Father; tō Theō kai Patri. Christ then is the great God, not figuratively, as magistrates and others are sometimes called gods, or as appearing and acting in the name of God, but properly and absolutely, the true God (1 John 5:20, the mighty God (Isaiah 9:6), who, being in the form of God, thought it not robbery to be equal with God, Philippians 2:6. In his second coming he will reward his servants, and bring them to glory with him. Observe,

Quoted verses:
Luke 9:26
For whosoever shall be ashamed of me and of my words, of him shall the Son of man be ashamed, when he shall come in his own glory, and in his Father's, and of the holy angels.

Hebrews 9:28
So Christ was once offered to bear the sins of many; and unto them that look for him shall he appear the second time without sin unto salvation.

1 Corinthians 15:24
Then cometh the end, when he shall have delivered up the kingdom to God, even the Father; when he shall have put down all rule and all authority and power.

1 John 5:20
And we know that the Son of God is come, and hath given us an understanding, that we may know him that is true, and we are in him that is true, even in his Son Jesus Christ. This is the true God, and eternal life.

Isaiah 9:6
For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his name shall be called Wonderful, Counsellor, The mighty God, The everlasting Father, The Prince of Peace.

Philippians 2:6
Who, being in the form of God, thought it not robbery to be equal with God:

[1.] There is a common and blessed hope for all true Christians in the other world. If in this life only they had hope in Christ, they were of all men the most miserable, 1 Corinthians15:19. By hope is meant the thing hoped for, namely, Christ himself, who is called our hope (1 Timothy 1:1), and blessedness in and through him, even riches of glory (Ephesians 1:18), hence fitly termed here that blessed hope.

Quoted verses:
1 Corinthians 15:19
If in this life only we have hope in Christ, we are of all men most miserable.

1 Timothy 1:1 [see Lesson]
Paul, an apostle of Jesus Christ by the commandment of God our Saviour, and Lord Jesus Christ, which is our hope;

Ephesians 1:18
The eyes of your understanding being enlightened; that ye may know what is the hope of his calling, and what the riches of the glory of his inheritance in the saints,

[2.] The design of the gospel is to stir up all to a good life by this blessed hope. Gird up the loins of your mind, be sober, and hope to the end for the grace that is to be brought unto you at the revelation of Jesus Christ, 1 Peter 1:13. To the same purport here, Denying ungodliness and worldly lusts, live soberly, righteously, and godly, in this present world, looking for the blessed hope; not as mercenaries, but as dutiful and thankful Christian. What manner of persons ought you to be in all holy conversation and godliness, looking for and hastening to the coming of the day of God! 2 Peter 3:11-12. Looking and hastening, that is, expecting and diligently preparing for it.  [Emphasis mine]

Quoted verses:
1 Peter 1:13
Wherefore gird up the loins of your mind, be sober, and hope to the end for the grace that is to be brought unto you at the revelation of Jesus Christ;

2 Peter 3:11-12
11 Seeing then that all these things shall be dissolved, what manner of persons ought ye to be in all holy conversation and godliness,
12 Looking for and hasting unto the coming of the day of God, wherein the heavens being on fire shall be dissolved, and the elements shall melt with fervent heat?

[3.] At, and in, the glorious appearing of Christ will the blessed hope of Christians be attained; for their felicity [the state of being happy] will be this, To be where he is, and to behold his glory, John 17:24. The glory of the great God and our Saviour will then break out as the sun. Though in the exercise of his judiciary power he will appear as the Son of man, yet will he be mightily declared to be the Son of God too. The divinity, which on earth was much veiled, will shine out then as the sun in its strength. Hence the work and design of the gospel are to raise the heart to wait for this second appearing of Christ. We are begotten again to a lively hope of it (1 Peter 1:3), turned to serve the living God, and wait for his Son from heaven, 1 Thessalonians 1:9-10. Christians are marked by this, expecting their Master's coming (Luke 12:36), loving his appearance, 2 Timothy 4:8. Let us then look to this hope; let our loins be girt, and our lights burning, and ourselves like those who wait for their Lord; the day or hour we know not, but he that shall come will come, and will not tarry, Hebrews 10:37.  [Emphasis mine]

Quoted verses:
John 17:24
Father, I will that they also, whom thou hast given me, be with me where I am; that they may behold my glory, which thou hast given me: for thou lovedst me before the foundation of the world.

1 Peter 1:3
Blessed be the God and Father of our Lord Jesus Christ, which according to his abundant mercy hath begotten us again unto a lively hope by the resurrection of Jesus Christ from the dead,

1 Thessalonians 1:9-10
9 For they themselves shew of us what manner of entering in we had unto you, and how ye turned to God from idols to serve the living and true God;
10 And to wait for his Son from heaven, whom he raised from the dead, even Jesus, which delivered us from the wrath to come.

Luke 12:36
And ye yourselves like unto men that wait for their lord, when he will return from the wedding; that when he cometh and knocketh, they may open unto him immediately.

2 Timothy 4:8 [see Lesson]
Henceforth there is laid up for me a crown of righteousness, which the Lord, the righteous judge, shall give me at that day: and not to me only, but unto all them also that love his appearing.

Hebrews 10:37
For yet a little while, and he that shall come will come, and will not tarry.

[4.] The comfort and joy of Christians are that their Saviour is the great God, and will gloriously manifest himself at his second coming. Power and love, majesty and mercy, will then appear together in the highest lustre, to the terror and confusion of the wicked, but to the everlasting triumph and rejoicing of the godly. Were he not thus the great God, and not a mere creature, he could not be their Saviour, nor their hope. Thus of the considerations to enforce the directions of all sorts to their respective duties from the nature and design of the gospel. And herewith is connected another ground.
 
 Now the Matthew Henry Concise. This commentary covers the rest of Chapter 2, verses 11-15.
 
The doctrine of grace and salvation by the gospel, is for all ranks and conditions of men. It teaches to forsake sin; to have no more to do with it. An earthly, sensual conversation suits not a heavenly calling. It teaches to make conscience of that which is good. We must look to God in Christ, as the object of our hope and worship. A gospel conversation must be a godly conversation. See our duty in a very few words; denying ungodliness and worldly lusts, living soberly, righteously, and godly, notwithstanding all snares, temptations, corrupt examples, ill-usage, and what remains of sin in the believer's heart, with all their hindrances. It teaches to look for the glories of another world. At, and in, the glorious appearing of Christ, the blessed hope of Christians will be complete: To bring us to holiness and happiness was the end of Christ's death. Jesus Christ, that great God and our Saviour, who saves not only as God, much less as Man alone; but as God-man, two natures in one person. He loved us, and gave himself for us; and what can we do less than love and give up ourselves to him! Redemption from sin and sanctification of the nature go together, and make a peculiar people unto God, free from guilt and condemnation, and purified by the Holy Spirit. All Scripture is profitable. Here is what will furnish for all parts of duty, and the right discharge of them. Let us inquire whether our whole dependence is placed upon that grace which saves the lost, pardons the guilty, and sanctifies the unclean. And the further we are removed from boasting of fancied good works, or trusting in them, so that we glory in Christ alone, the more zealous shall we be to abound in real good works. ~Matthew Henry Concise    [Emphasis mine]
 
 Now to the specific commentaries.
 
 This verse is broken out in different ways but we will go with this one.

1] Looking for.
2] That blessed hope.
3] The glorious appearing.
4] Of the great God and our Saviour Jesus Christ,

1] Looking for.
Looking for - Expecting; waiting for. That is, in the faithful performance of our duties to ourselves, to our fellow-creatures, and to God, we are patiently to wait for the coming of our Lord.
(1) We are to believe that he will return;
(2) We are to be in a posture of expectation, not knowing when he will come; and,
(3) We are to be ready for him whenever he shall come; see the Matthew 24:42-44 notes; 1 Thessalonians 5:4 note; Philippians 3:20 note.

Quoted verses:
Matthew 24:42-44
42 Watch therefore: for ye know not what hour your Lord doth come.
43 But know this, that if the goodman of the house had known in what watch the thief would come, he would have watched, and would not have suffered his house to be broken up.
44 Therefore be ye also ready: for in such an hour as ye think not the Son of man cometh.

1 Thessalonians 5:4
But ye, brethren, are not in darkness, that that day should overtake you as a thief.

Philippians 3:20
For our conversation is in heaven; from whence also we look for the Saviour, the Lord Jesus Christ:

2] That blessed hope.

That blessed hope - The fulfillment of that hope so full of blessedness to us.

3] The glorious appearing.

The glorious appearing - Notes, 2 Thessalonians 2:8; compare 1 Timothy 6:14; 2 Timothy 1:10; 2 Timothy 4:8.

Quoted verses:
2 Thessalonians 2:8
And then shall that Wicked be revealed, whom the Lord shall consume with the spirit of his mouth, and shall destroy with the brightness of his coming:

1 Timothy 6:14 [see Lesson]
That thou keep this commandment without spot, unrebukeable, until the appearing of our Lord Jesus Christ:

2 Timothy 1:10 [see Lesson]
But is now made manifest by the appearing of our Saviour Jesus Christ, who hath abolished death, and hath brought life and immortality to light through the gospel:

2 Timothy 4:8 [see Lesson]
Henceforth there is laid up for me a crown of righteousness, which the Lord, the righteous judge, shall give me at that day: and not to me only, but unto all them also that love his appearing.

4] Of the great God and our Saviour Jesus Christ,

Of the great God and our Saviour Jesus Christ - There can be little doubt, if any, that by “the great God” here, the apostle referred to the Lord Jesus, for it is not a doctrine of the New Testament that God himself as such, or in contradistinction from his incarnate Son, will appear at the last day. It is said, indeed, that the Saviour will come “in the glory of his Father, with his angels” Matthew 16:27, but that God as such will appear is not taught in the Bible. The doctrine there is, that God will be manifest in his Son; that the divine approach to our world be through him to judge the race; and that though he will be accompanied with the appropriate symbols of the divinity, yet it will be the Son of God who will be visible. No one, accustomed to Paul’s views, can well doubt that when he used this language he had his eye throughout on the Son of God, and that he expected no other manifestation than what would be made through him.

Quoted verse:
Matthew 16:27
For the Son of man shall come in the glory of his Father with his angels; and then he shall reward every man according to his works.

In no place in the New Testament is the phrase Theou - “the manifestation or appearing of God” - applied to any other one than Christ. It is true that this is spoken of here as the “appearing of the glory - of the great God,” but the idea is that of such a manifestation as became God, or would appropriately display his glory. It is known to most persons who have attended to religious controversies, that this passage has given rise to much discussion. The ancients, in general, interpreted it as meaning” The glorious appearing of our great God and Saviour Jesus Christ.”  ~Barnes Notes

So look for that blessed hope, for this is the lesson of verse 13.
