It is our will that makes us able to follow one or the other and to separate the two. The Spirit is that which is a connection to God, and all that He is. So we have God the Father as the soul, Jesus is the body, and the Holy Spirit is the Spirit. It is the name of God. God is not 3 separate parts but one, Who at one time went an extra mile for us and descended to this earth as a man and took our sin unto Himself so we could be saved from death, hell, and the grave.
Baptism is something that gets more people mad than almost any other subject.
Compare 1954, 3442. To baptize is to immerse. It does not mean dunk in water. There is another aspect of this, the immersion requires the Holy Spirit. If you are one who believes that the Holy Spirit was only in Acts or it is over rated, then you have a problem with God, because He is a Spirit, and His Spirit is holy.
