Let him who boast boast in The Lord

Therefore, as it is written: "Let him who boasts boast in the Lord.
1 Corinthians 1:31

Do nothing out of selfish ambition or vain conceit, but in humility consider others better than yourselves.
Philippians 2:3

God "will give to each person according to what he has done."
Romans 2:6

"I the LORD search the heart and examine the mind, to reward a man according to his conduct, according to what his deeds deserve."
Jeremiah 17:10

We do not dare to classify or compare ourselves with some who commend themselves. When they measure themselves by themselves and compare themselves with themselves, they are not wise. We, however, will not boast beyond proper limits, but will confine our boasting to the field God has assigned to us, a field that reaches even to you. We are not going too far in our boasting, as would be the case if we had not come to you, for we did get as far as you with the gospel of Christ. Neither do we go beyond our limits by boasting of work done by others. Our hope is that, as your faith continues to grow, our area of activity among you will greatly expand, so that we can preach the gospel in the regions beyond you. For we do not want to boast about work already done in another man's territory. But, "Let him who boasts boast in the Lord."
2 Corinthians 10:12-17

Do not be wise in your own eyes; fear the LORD and shun evil.
Proverbs 3:7

Do not judge, or you too will be judged. For in the same way you judge others, you will be judged, and with the measure you use, it will be measured to you.
Matthew 7:1-2

If anyone thinks he is something when he is nothing, he deceives himself.. Each one should test his own actions. Then he can take pride in himself, without comparing himself to somebody else, for each one should carry his own load. Anyone who receives instruction in the word must share all good things with his instructor. Do not be deceived: God cannot be mocked. A man reaps what he sows.
Galatians 6:3-7

For it is not the one who commends himself who is approved, but the one whom the Lord commends.
2 Corinthians 10:18
