Add/supplement to your faith, lambs and sheep of CHRIST in HIS unworthy servant's prophesy that, JESUS named Simon as Peter, meaning the 'Rock', and in whom CHRIST will build HIS church upon and Apostle Peter said this in the book of Acts, saying;
"Can anyone stop us from baptizing people with water."
And Philip was earnestly looking for water to baptize a Eunuch(Gentile), in the same book, even proclaimed as 'The Acts of the Apostles'.
But most importantly what JESUS said to Nicodemus.
Apostle Paul did not forbid physical water Baptism but only added revelation knowledge to their initial faith, to grow further in faith in order to practice Spiritual baptism, with the HOLY SPIRIT who leads them to lead others into the full truth, 'that is to bury the old man of carnality/flesh with CHRIST and resurrect with CHRIST as a new creature to Spirituality'.
And JESUS said this to HIS disciples, and proclaimed in the Gospel of John, that is one of the HELPER duty to them, 'to lead them into the full truth'.
