Acts 1:5 for John truly baptized with water, but you shall be baptized with the Holy Spirit not many days from now.”
John's water baptism was a person's public announcement that he had repented of his sins. John's water baptism did not forgive sins. Jesus had not yet been sacrificed so this water baptism could not forgive sins. Also, this water baptism was not done as Jesus commanded in Matthew 28:18-19 because Jesus gave this commandment after He rose from the dead. John baptized people before Jesus rose from the dead. John died before Jesus died on the cross. John's baptism did not forgive sins.
This is about the laying on of hands by the apostles which is the Baptism of the holy Spirit with fire.
Acts 8:17 These are invisible tongues of fire. It seems only the apostles were chosen on that first Pentecost Sunday to receive the
visible tongues of fire directly from God.
The sea is made of water. The Red Sea drowned all the Egyptians so the Israelites were saved by the water of the Red Sea. This water did not forgive their sins.
You are perhaps overthinking about this subject.
The baptism commanded by Jesus is the water baptism which forgives Adam's sin (we were born with his sin on our souls). None of the other baptisms forgives Adam's sin. The blessed water of this baptism of Jesus is the conduit by which the blood merits of Jesus' sacrifice are applied to our souls and this baptism is what washes away Adam's sin and our sins and so it is this water baptism which initially saves us. Acts 22:16
God does not have to follow the commands that He gave to His Church leaders but God's Church leaders do have to follow His commands. That is why even though some Gentiles received the Holy Spirit before they were water baptized Acts 10:47, they still were required to be water baptized according to Jesus' command in Matthew 28:18-19.
