In response to the above question
Baptism is part of the fulfilment of what was written.
Let look at Matthew 3:13-15
Then cometh Jesus from Galilee to Jordan unto John, to be baptized of him .
(14) But John for bad him, saying I have need to be baptized of thee, and cometh thou to me?
(15) And Jesus answering said unto him, suffer it to be so now: for thus is becometh us to fill all righteousness. Then he suffered him.
Jesus came to fulfill all righteousness.
Let look at Hebrews 10: 7
Then said I, lo, I come (in the volume of the book it is written of me) to do will, o God. Also the book of Isaiah 40: 3.
The voice of him that crieth in the wilderness, prepare ye the way of the Lord, make straight in the desert a highway for our God.
The above scripture has prophecy before Jesus Christ was born concerning his baptism and that is what he went to fulfill in
Matthew 3:13
Then cometh Jesus from Galilee to Jordan unto John., to be baptized of him. May the Lord give us more knowledge and understanding to hear his word.
