4 Bible Verses about Justification Excluding Boasting

Then what becomes of our boasting? It is shut out. On what principle? What a man does? No, but whether a man has faith. For we hold that a man is made upright by faith; the observance of the Law has nothing to do with it.

For if he was made upright by what he did, it is something to be proud of. But not to be proud of before God,

and it was what the world calls low and insignificant and unreal that God chose to nullify its realities,

For it is by his mercy that you have been saved through faith. It is not by your own action, it is the gift of God.
