How do we know God justifies the ungodly?

The concept of God justifying the ungodly is profoundly established in Scripture, particularly in Romans 4. God does not base justification on human effort or righteousness, but solely on the merit of Christ’s obedience and sacrifice. This justification is a free gift, received through faith. Ephesians 2:8-9 reinforces that salvation is by grace alone, not by works, ensuring that no one can boast of their standing before God. This foundational truth shows that God’s grace is available to all who believe, regardless of their past, proving that true righteousness comes through faith in Christ's redemptive work.
