Why is it important that Christ's sacrifice is finished?

The finished nature of Christ's sacrifice is vitally important for several reasons. First, it assures believers that their sins are fully atoned for and that they stand justified before God. Romans 8:1 reinforces this truth: 'There is therefore now no condemnation for those who are in Christ Jesus.' This reality liberates Christians from the legalistic notion that they must earn their salvation through works. Second, knowing that Christ's sacrifice is completed fosters a foundation of peace, joy, and security in one's relationship with God. Believers can rest assured that their standing before God is based solely on Christ's righteousness, not their own efforts or failures.
