How do we know the blood of Christ is effective for salvation?
Answered in 2 sources
The effectiveness of Christ's blood for salvation is affirmed by its divine appointment and the sinlessness of the Savior.
The blood of Christ is effective for salvation because it was ordained by God Himself as the sole means of atonement. In Acts 20:28, we learn that God purchased the church with His own blood, indicating that it is not just any blood, but the blood of the sinless God-man. This unique quality grants it the power to cleanse us from our sins completely, establishing a covenant between God and those He redeems. Furthermore, the perfect nature of Christ’s sacrifice ensures that no human merit or action can contribute to our salvation; it rests solely on His work.
