Acts 2:38
38Peter said to them, “Repent, and each of you be baptized in the name of Jesus Christ for the forgiveness of your sins; and you will receive the gift of the Holy Spirit.
I want to suggest that there is a fourth baptism – the baptism in the name of Jesus. The bible says to repent or change your thinking. Accept Jesus as the Christ. It would seem that you are then and immediately baptized in the name – the Name above all names, even Jesus. When you are baptized in this Name, you are saved. And, you get the added love of the gift of the Holy Spirit.
The water baptism doesnt bring salvation, although it is to be done. It is the baptism in the Name of Jesus that brings salvation.
