i think more accurately, in preaching Jesus the Christ, the gospel of His work and His person is preached. water immersion is instructed after preaching and performed after preaching, hearing, believing and calling. and everyone who calls on Him will be saved!
Lets turn to the book of Acts for a moment...
Acts 8:26 And the angel of the Lord spake unto Philip, saying, Arise, and go toward the south unto the way that goeth down from Jerusalem unto Gaza, which is desert.
[27] And he arose and went: and, behold, a man of Ethiopia, an eunuch of great authority under Candace queen of the Ethiopians, who had the charge of all her treasure, and had come to Jerusalem for to worship,
[30] And Philip ran thither to him, and heard him read the prophet Esaias, and said, Understandest thou what thou readest?
[31] And he said, How can I, except some man should guide me? And he desired Philip that he would come up and sit with him.
[32] The place of the scripture which he read was this, He was led as a sheep to the slaughter; and like a lamb dumb before his shearer, so opened he not his mouth:
[33] In his humiliation his judgment was taken away: and who shall declare his generation? for his life is taken from the earth.
[34] And the eunuch answered Philip, and said, I pray thee, of whom speaketh the prophet this? of himself, or of some other man?
Now this is where I'm going with this...
Acts 8:35 Then Philip opened his mouth, and began at the same scripture, and
preached unto him Jesus.
[36] And as they went on their way, they came unto a certain water: and the eunuch said, See,
here is water; what doth hinder me to be
baptized?
In the PREACHING of JESUS we see that Water Baptism was preached, which is in accordance with Peter's reply in Acts 2:38. And preaching water baptism is the burial with Christ...
Romans 6:3 Know ye not, that so many of us as were baptized into Jesus Christ were baptized into his death?
[4] Therefore we are
buried with him by baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life.
