How does one attain righteousness according to the Bible?

The Bible teaches that righteousness before God is not achieved through works but is a gracious gift received by faith in Jesus Christ. As stated in Isaiah 45:24, 'Surely, shall one say, in the Lord have I righteousness.' This righteousness is attributed to believers because of Christ's work — His life, death, and resurrection — fulfilling all righteousness required by the law. We see this confirmed in the New Testament, particularly in 2 Corinthians 5:21, where it states that Christ was made sin for us, so that we might become the righteousness of God in Him. This understanding positions faith as the means through which we are justified, not by our works but through Christ's imputed righteousness.
