How do we know Jesus' sacrifice is sufficient for our salvation?

The sufficiency of Jesus' sacrifice is anchored in numerous scriptures that detail His role as the Lamb of God who takes away the sins of the world. For instance, 2 Corinthians 5:21 explains that God made Christ to be sin for us so that we could become the righteousness of God through Him. This definitive act on the cross underscores the absolute nature of His atonement. Furthermore, Hebrews 9:12 tells us that by His own blood, He obtained eternal redemption for us, indicating that His sacrifice is not only adequate but fully effective for securing our salvation. Therefore, we rely on His completed work, affirming that nothing else is needed for our justification.
