At Calvary, we see an unjust scene when mankind nailed the Lord Jesus to a cross. The Bible tells us that since sin came into the Garden of Eden all men have sinned and fallen short of the glory of God. Mankind has tried to earn favour with God through their good works but there is only one way we can be brought back to God by the work of the Lord Jesus Christ. What can wash away our sin? Nothing but the blood of Jesus.
