The Cross Introduction Jesus is the only begotten Son of God. His purpose was to be the lamb of God to give His life as perfect sacrifice for the sin of any human who will accept His death as substitution for our sins. Sin separates us from God Who cannot be in the presence of sin. Eternal separation from the presence of God is known as Hell. Jesus became the curse for our sins as He hung on the cross.
All religions teach that a sacrifice is necessary for forgiveness of sins.
There is no forgiveness of sins without shedding of perfect blood. Jesus' blood is the only perfect blood because Jesus has never committed sin. Jesus was tempted to sin as all mankind is tempted, but He did not yield to sin. Jesus was the perfect lamb of God, like the Passover lamb whose blood over the doorpost of the house prevented entry of the death angel. The blood of Jesus, the lamb of God who died on the cross, applied to our lives by faith, removes our sins.
