What does the Bible say about how God justifies the ungodly?

The Bible teaches that God justifies the ungodly entirely by His grace and the righteousness of Christ. This concept is exemplified in Abraham's life, who is seen as a prime example in Romans chapter four. God called Abraham out of idolatry and into a covenant relationship, demonstrating that justification is not based upon human merit or lineage, but upon faith in God's promise. Just as Abraham looked forward to the promise of Christ, believers today are justified by faith in the finished work of Christ– a gift from God, not dependent on our works.
