How do we know that Jesus is the only solution for our sin?

The New Testament consistently affirms Jesus as the sole remedy for sin and its consequences. As noted in Matthew 1:21, His very name signifies His mission: 'He shall save His people from their sins.' Through His atoning sacrifice on the cross, He deals with the guilt and power of sin, bringing forgiveness and cleansing (1 John 1:7). Thus, believing in Him is the only way to receive both spiritual healing and a transformed life, making Him the indispensable solution for our sinful condition.
