Yes I agree. Obedience is better than sacrifice. Disobedience is what got us into this mess. Of course Jesus was both obedience and sacrificeBaptism is the Sacrament of initiation into the Body of Christ. It is a statement that the parents and family are not going to raise their child in worldly ways, the way of Adam and Eve, but in the way of God as a follower and discipleship (discipline of) Christ. It is a statement that the child will be raised in obedience to the Way of Christ (I am the way the truth and the life) rather than the path of disobedience chosen by Adam and Eve.
Baptism is obedience but also symbolic of rebirth. When you are born you go from being in water or amniotic fluid to being born. The Bible says we must be born again. Our baptism is symbolic of that rebirth. We once again emerge from the water and into the spirit. This was seen at Jesus’s baptism when the spirit in the form of a dove descended on Jesus and God said “This is my Son, whom I love; with him I am well pleased.”
Not being able to enter the kingdom unless you are born of water and spirit and child mortality being so high until recently, it’s understandable why the church and parents would want that process to begin ASAP rather than waiting until they become adults.
I was baptized as a baby but redid my baptism as an adult shortly after accepting Christ as my Lord and Savior. It was an act of obedience but also a public declaration and commitment of my faith.
Mathew 3:16 As soon as Jesus was baptized, he went up out of the water. At that moment heaven was opened, and he saw the Spirit of God descending like a dove and alighting on him. 17 And a voice from heaven said, “This is my Son, whom I love; with him I am well pleased.”
