ACCEPTABLE BOASTING ***
Here are verses about acceptable boasting:

1 Corinthians 1: Paul, called by the will of God to be an apostle of Christ Jesus, and our brother Sos’thenes, 2 To the church of God which is at Corinth, to those sanctified in Christ Jesus, called to be saints together with all those who in every place call on the name of our Lord Jesus Christ, both their Lord and ours: 3 Grace to you and peace from God our Father and the Lord Jesus Christ. 4 I give thanks to God always for you because of the grace of God which was given you in Christ Jesus, 5 that in every way you were enriched in him with all speech and all knowledge– 6 even as the testimony to Christ was confirmed among you– 7 so that you are not lacking in any spiritual gift, as you wait for the revealing of our Lord Jesus Christ; 8 who will sustain you to the end, guiltless in the day of our Lord Jesus Christ. 9 God is faithful, by whom you were called into the fellowship of his Son, Jesus Christ our Lord. 10 I appeal to you, brethren, by the name of our Lord Jesus Christ, that all of you agree and that there be no dissensions among you, but that you be united in the same mind and the same judgment. 11 For it has been reported to me by Chlo’e’s people that there is quarreling among you, my brethren. 12 What I mean is that each one of you says, “I belong to Paul,” or “I belong to Apol’los,” or “I belong to Cephas,” or “I belong to Christ.” 13 Is Christ divided? Was Paul crucified for you? Or were you baptized in the name of Paul? 14 I am thankful that I baptized none of you except Crispus and Ga’ius; 15 lest any one should say that you were baptized in my name. 16 (I did baptize also the household of Steph’anas. Beyond that, I do not know whether I baptized any one else.) 17 For Christ did not send me to baptize but to preach the gospel, and not with eloquent wisdom, lest the cross of Christ be emptied of its power. 18 For the word of the cross is folly to those who are perishing, but to us who are being saved it is the power of God. 19 For it is written, “I will destroy the wisdom of the wise, and the cleverness of the clever I will thwart.” 20 Where is the wise man? Where is the scribe? Where is the debater of this age? Has not God made foolish the wisdom of the world? 21 For since, in the wisdom of God, the world did not know God through wisdom, it pleased God through the folly of what we preach to save those who believe. 22 For Jews demand signs and Greeks seek wisdom, 23 but we preach Christ crucified, a stumbling block to Jews and folly to Gentiles, 24 but to those who are called, both Jews and Greeks, Christ the power of God and the wisdom of God. 25 For the foolishness of God is wiser than men, and the weakness of God is stronger than men. 26 For consider your call, brethren; not many of you were wise according to worldly standards, not many were powerful, not many were of noble birth; 27 but God chose what is foolish in the world to shame the wise, God chose what is weak in the world to shame the strong, 28 God chose what is low and despised in the world, even things that are not, to bring to nothing things that are, 29 so that no human being might boast in the presence of God. 30 He is the source of your life in Christ Jesus, whom God made our wisdom, our righteousness and sanctification and redemption; 31 therefore, as it is written, “Let him who boasts, boast of the Lord.”

2 Corinthians 1:14 NIV as you have understood us in part, you will come to understand fully that you can boast of us just as we will boast of you in the day of the Lord Jesus.

2 Corinthians 7:14 NIV I had boasted to him about you, and you have not embarrassed me. But just as everything we said to you was true, so our boasting about you to Titus has proved to be true as well.

2 Corinthians 9:2 NIV For I know your eagerness to help, and I have been boasting about it to the Macedonians, telling them that since last year you in Achaia were ready to give; and your enthusiasm has stirred most of them to action.

2 Corinthians 9:3 NIV  But I am sending the brothers in order that our boasting about you in this matter should not prove hollow, but that you may be ready, as I said you would be.

2 Corinthians 10:8 NIV For even if I boast somewhat freely about the authority the Lord gave us for building you up rather than pulling you down, I will not be ashamed of it.

2 Corinthians 10:13-17 NIV  But we will not boast beyond limit, but will keep to the limits God has apportioned us, to reach even to you. 14 For we are not overextending ourselves, as though we did not reach you; we were the first to come all the way to you with the gospel of Christ. 15 We do not boast beyond limit, in other men’s labors; but our hope is that as your faith increases, our field among you may be greatly enlarged, 16 so that we may preach the gospel in lands beyond you, without boasting of work already done in another’s field. 17 “Let him who boasts, boast of the Lord.”

2 Corinthians 11:10-21 NIV As the truth of Christ is in me, this boast of mine shall not be silenced in the regions of Acha’ia. 11 And why? Because I do not love you? God knows I do! 12 And what I do I will continue to do, in order to undermine the claim of those who would like to claim that in their boasted mission they work on the same terms as we do. 13 For such men are false apostles, deceitful workmen, disguising themselves as apostles of Christ. 14 And no wonder, for even Satan disguises himself as an angel of light. 15 So it is not strange if his servants also disguise themselves as servants of righteousness. Their end will correspond to their deeds. 16 I repeat, let no one think me foolish; but even if you do, accept me as a fool, so that I too may boast a little. 17 (What I am saying I say not with the Lord’s authority but as a fool, in this boastful confidence; 18 since many boast of worldly things, I too will boast.) 19 For you gladly bear with fools, being wise yourselves! 20 For you bear it if a man makes slaves of you, or preys upon you, or takes advantage of you, or puts on airs, or strikes you in the face. 21 To my shame, I must say, we were too weak for that! But whatever any one dares to boast of–I am speaking as a fool–I also dare to boast of that.

Philippians 2:14-16 NIV Do all things without grumbling or questioning, 15 that you may be blameless and innocent, children of God without blemish in the midst of a crooked and perverse generation, among whom you shine as lights in the world, 16 holding fast the word of life, so that in the day of Christ I may be proud that I did not run in vain or labor in vain.

2 Thessalonians 1:4 NIV  Therefore, among God’s churches we boast about your perseverance and faith in all the persecutions and trials you are enduring.

Hebrews 3:6 NIV But Christ is faithful as a son over God’s house. And we are his house, if we hold on to our courage and the hope of which we boast.
