Actually Baptism eba part of the Fulfilment of what is written. It is a part of fulfilment

But John forbad him, saying, I have need to be baptized of thee, and comest thou to me?
And Jesus answering said unto him, Suffer it to be so now: for thus it becometh us to fulfil all righteousness. Then he suffered him.
Jesus came to fulfill all righteousness
Hebrews 10:7 Then said I, Lo, I come (in the volume of the book it is written of me,) to do thy will, O God.
There are those things that Jesus came to earth to fulfill which Baptism is included and it is a will of God
Luke 24:44 And he said unto them, These are the words which I spake unto you, while I was yet with you, that all things must be fulfilled, which were written in the law of Moses, and in the prophets, and in the psalms, concerning me.
There are things to fulfill concerning Jesus Christ and he fulfil them
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.
Baptism of John the Baptism of repentance and forgiveness of sin, being officiated by John in the river Jordan and other rivers he performed it
