How do we know the blood of Jesus is powerful?

The effectiveness of Jesus’ blood in the life of a believer is affirmed in multiple scripture passages, such as 1 John 1:7, which states, 'The blood of Jesus Christ, God's Son, cleanses us from all sin.' This cleansing is essential for our salvation, allowing us to stand before God blameless. Additionally, in 1 Peter 1:18-19, the apostle Peter emphasizes that we were redeemed not with corruptible things, but by the precious blood of Christ, highlighting its unmatched value. Therefore, the blood is not merely a symbol but the means by which God’s justice is satisfied and His grace is applied to believers.
