4 Bible Verses about Justification Excluding Boasting

So where has human boasting gone? It was completely shut out. On what principle? On that of doing something? No, but on the principle of faith. For we hold that a man is brought into right standing with God by faith, that observance of the law has no connection with it.

For if he was considered in right standing with God on the condition of what he did, he has something to boast of, but not before God.

what the world calls of low degree, yea, what it counts as nothing and what it thinks does not exist, God chose to put a stop to what it thinks exists,

For it is by His unmerited favor through faith that you have been saved; it is not by anything that you have done, it is the gift of God.
