This pointed to Jesus who became the Lamb of God, and sacrificed His own life (John 10:17), “who takes away [our] sin” so that we might be delivered from death which sin has brought on the human race. Paul helps us understand this pivotal event in 2 Corinthians 5:21; “For our sake he (God) made him (Jesus) to be sin who knew no sin, so that in him we might become the righteousness of God.” The removal of our sin by Jesus the Lamb, makes us right with God.
The cross of Christ was the highest price paid for sin, but in paying that price Jesus took away sin for God and for those who believe in Him. “But the free gift is not like the trespass [sin]. For if many died through one man’s trespass, much more have the grace of God and the free gift by the grace of that one man Jesus Christ abounded for many.” (Romans 5:15). I trust that you have received this “free gift” by faith through repentance. No wonder this is called GOOD FRIDAY!
