The authority of baptism is the fact that God has made Jesus the Lord over all and the Christ who will restore world righteousness as light of the world. All things are being made more and more subject to Jesus. He is teacher of righteousness for all who died for all to purify from sin. This is because God is pleased in how Jesus obeyed Him even when it meant dying on the cross. The only one not subject to Jesus is forever going to be the Father, God. The baptism in the name, the authority, the way of Jesus is by the authority the Father gave Jesus and is therefore the authority of the Father and the Holy Spirit too. It is all about holding to the teachings, the commands, the persuasions which come from Jesus who receives them from the Father. It is about taking on board these commands and teachings and persuasions. This is what is called ”taking his yoke”, like the yoke oxen were given before starting to plough. Baptism is taking this upon yourself, as you start a life of cutting a straight furrow in his name (oxen, plough, furrow metaphor for living a life under the tutelage of the teachings of the Lord Jesus Christ), believing he is the Son of God: Believing God is the Father of Jesus Christ, raised from the dead by the Father to live forever to help those who believe in him to forever stay right with God.
