Baptism with water is the sign and seal of baptism with the Spirit, as much as it is of the forgiveness of sins. Water-baptism is the initiatory Christian rite, because Spirit-baptism is the initiatory Christian experience.
John StottIf we truly worship God, acknowledging and adoring his infinite worth, we find ourselves impelled to make him known to others, in order that they may worship him too. Thus worship leads to witness, and witness in its turn to worship, in a perpetual circle.
