FAQ on the Christian Faith
God gave Israel His Law through Moses as well as the sacrificial system so that they could attain atonement for their sins and iniquities. He ordained Aaron, the elder brother of Moses, as the High Priest and had him offer the sacrifice of atonement on the tenth day of the seventh month, the Day of Atonement, so that the yearly sins of Israel could be washed away (Leviticus 16).
God specified that the sacrifice of the Day of Atonement could only be offered by Aaron and the succeeding High Priests among his descendants. God opened the way for Israelites to atone for all their sins through the laying on of Aaron's hands on the head of the scapegoat. This is the law of atonement God established for them.
By this shadow, He let it be known clearly that Jesus was the Savior of mankind. In the age of the New Testament, God sent John the Baptist, a descendant of Aaron (1 Chronicles 24:10, Luke 1:5) and the last High Priest of the Old Testament (Matthew 11:11-13). John the Baptist, as the God-sent prophet, representative and High Priest of humankind, baptized Jesus in order to pass all the sins of humankind onto Him, the Son of God, who came to save sinners.
All people are blessed indeed to be able to pass their sins onto Jesus through John the Baptist. The role of John was to be the High Priest who represented humankind and the servant of God who passed all our sins onto Jesus.
John the Baptist was the representative and the High Priest of humankind sent by God, and the messenger who was sent 6 months prior to Jesus. On the other hand, Jesus was the Lamb of God who took away all the sins of the world while John the Baptist was the last High Priest who passed the sins of the world onto Jesus through baptism. John the Baptist was a servant of God.
