You submit yourself to be baptized because of fulfilling your righteousness. We ourselves must follow that example.
This situation does not necessarily need us to be in accordance to our expectation of what we think it should be, but because we must feel that perfect will of God.
Jesus Christ is the Lord, the Son of God.
He has not committed any sin before. He has no sin that needed to be washed away by baptism in the body. Because being our leader, he was showing us the way we must follow.
Baptism is a doctrine of the church that we must follow. We are not to argue. There is no question that the master told us that every person who believes in God must be baptized in the name of the Father, and the Son, and the Holy Spirit.
We must adhere to the teaching of God as obedient children and as true disciples. Let us submit ourselves to that baptism.
