Why baptism?

 Baptism

Purpose: Wash away sin and to wash away the person's pre-conversion life as they transition to a "christian life".

History: John the Baptist performed the ritual before christianity began. Jesus was baptized by John the Baptist. Jews use a mikvah for ritual cleansing.

However, we have no record of Jesus ever baptizing anyone, recommending baptism, or ensuring anyone was baptized.

Okay. Let's go through some of this. We're taught that we only have one baptism for the remission of sin.  (Remission: cancellation or forgiveness).Wash away sin? Do I have to be baptized every time I need to be cleansed of my sin or is it an act that is only done once per person?  Only once?, then why do I have to do it? Why not simply repent and ask God for forgiveness? That's all a person has to do all the other times.

Proclamation of a transition from an old life to "a life in Christ"? Isn't that "confirmation"? Do we have to transition twice?

Infant baptism? How can an infant confirm their commitment to a christian life? Or is infant baptism simply a little presumptuous for parents to give their child a bath in public?

I'm not sure baptism is all that important for someone to live their life according to God's message.
