Why is knowing about righteousness important for Christians?

For Christians, comprehending righteousness is vital because it fundamentally informs their relationship with God and their standing before Him. According to Romans 10:3, many are 'ignorant of God's righteousness, and going about to establish their own righteousness have not submitted themselves unto the righteousness of God.' This highlights the necessity of recognizing that true righteousness can only come through faith in Christ. Furthermore, knowing that righteousness is a gift enables believers to live in assurance and gratitude, as they understand that it is not their works that justify them but Christ's perfect sacrifice. Philippians 3:8-9 underscores this truth, causing Christians to place their confidence solely in Christ’s righteousness instead of their own flawed efforts.
