“The next day John saw Jesus coming toward him and said,
‘Look, the lamb of God, who takes away the sin of the world.’”
John 1:29 (NIV)
John the Baptist’s father was a priest. “He was familiar with all the ritual of the temple and its sacrifices.”1 He must have seen the morning and evening offering of a lamb to God. The offering of a lamb brought atonement for the sins of the people. “The people performed this ritual even when they starved in war and in siege they never omitted to offer the lamb until A. D. 70 when the temple was destroyed.”2
Jesus freely gave himself to be the sacrifice “once for all.”(Hebrews 10:10) Because of His offering on Calvary, we don’t have to give sacrifice for our sins. He died for us that we might be deemed worthy to join Him and His Father in heaven at the time He calls us home.
