that's not really what it says there -
"When He had been baptized, Jesus came up immediately from the water; and behold, the heavens were opened to Him, and He saw the Spirit of God descending like a dove and alighting upon Him. 17 And suddenly a voice came from heaven, saying, “This is My beloved Son, in whom I am well pleased.” Matt 3
the Holy Spirit works to help facilitate the work of Messiah
I suppose the Spirit of God rode Jesus's back like a horse?
