How is righteousness attained according to the Bible?

The Bible teaches that righteousness is attained by grace through faith, not through human effort or adherence to the law. In Romans 9:30, Paul contrasts those who sought righteousness by works with those who received it by faith, illustrating that righteousness cannot be earned or merited. Ephesians 2:8-9 emphasizes that grace is the unmerited favor of God, making it clear that faith is a gift from God and not a work we accomplish on our own. Believing in Christ means resting in His completed work for our righteousness, which is essential for salvation.
