Justification by faith in the Bible

The doctrine of justification by faith is one of the central tenants of Protestant theology. Justification refers to right legal standing before God. It’s theological concept that’s seen throughout the Bible. We see it in Abraham who believed in God and had his faith counted as righteousness. We see the idea in the Bible’s most well known verse, John 3:16. And we see it throughout the writings of Paul. Here are several verses which help us with a theology of justification by faith.

Abraham responding in faith to God’s covenant promises.
Genesis 15:6 
Then he believed in the LORD; and He reckoned it to him as righteousness.

Paul looks back at Abraham’s faith in helping Christians understand the importance of faith.
Galatians 2:16
knowing that a man is not justified by the works of the Law but through faith in Christ Jesus, even we have believed in Christ Jesus, so that we may be justified by faith in Christ and not by the works of the Law; since by the works of the Law no flesh will be justified.

Romans 4:2
For if Abraham was justified by works, he has something to boast about, but not before God.

Romans 3:28
For we maintain that a man is justified by faith apart from works of the Law.

Verses which specifically mention justification by faith
Romans 5:1
Therefore, having been justified by faith, we have peace with God through our Lord Jesus Christ
