Four Reasons for Jesus' Baptism

There are at least four purposes for the baptism of Jesus, he's our example in all righteousness in Matthew 3:15. To be anointed by the father. The Old Testament prophets, priests, and kings were always anointed in some way to signify that they were chosen of God (Exodus 28:41; 29:7; I Kings 19:16). The oil with which they were anointed was symbolic of the Holy Ghost. Jesus, then, in like manner was to be anointed by the Holy Ghost since He came to fulfill the roles of prophet, priest, and king (Psalm 45:7-8; Hebrews 4:14; Isaiah 61:1). It was after Jesus' baptism that He stood in the synagogue at Nazareth and proclaim the fulfillment of Isaiah's prophecy in Himself saying, "The Spirit of the LORD is upon me, because he hath anointed me to preach the gospel to the poor; he hath sent me to heal the brokenhearted, to preach deliverance to the captives, and recovering of sight to the blind, to set at liberty them that are bruised, to preach the acceptable year of the LORD" (Luke 4:18; anointed by God in 3:21-23).
