What God had done that night is to confirm His word in me by that sign. Only then did I know what prophecy really meant. I know that God's true prophets will agree. Of those who disagree, I know that I can challenge any number of would-be prophets, if need be I could take them behind the woodshed of the Holy Ghost and thrash each of them with spiritual power, putting them all to shame. Not only myself but also any true prophet of God in these last days should have that confidence and power .
Baptism is an action that suggests a total immersion.
John's water baptism was for repentance and a preparation for the spiritual baptism, the promised Baptism with the Holy Ghost comes from the Father and in it we receive power. The Baptism with the Holy Ghost first occurred on the day of Pentecost following the ascension . This is a New Testament phenomenon, there are instances of those in the Old Testament that were filled with the Holy Ghost, but never a total baptism. This breathing on the disciples was the Holy Ghost but was still not the Baptism with the Holy Ghost because Jesus told them later when it would be. For John truly baptized with water, but you shall be baptized with the Holy Ghost not many days hence.
