Water baptism gets you wet... nothing else.
Let me show you again.
In Acts 2:36, the Jews were told that "you've slain (crucified) your messiah".. and they (the Jews) said.. "what must we do".
A.) repent and get wet.
So, that is not the Gospel.. That is "john the baptist's water dunk, that was happening to Jews, before Jesus was crucified.
And Peter taught THAT, because that is all he knew at the time.
In Acts 15, He met Paul, and learned : "The Gospel of the Grace of God", ... and that is "the preaching of the Cross.
That's the "GOSPEL"............not, "repent and get wet".
Notice, Paul's Gospel, that Paul said that HIS the only gospel, and any other is "cursed"... : Galatians 1:8
And Paul did not preach "repent and get wet"...
He Preached THIS Gospel.........."The Preaching of THE CROSS....Is the POWER OF GOD.... unto SALVATiON, for everyone who BELIEVES".
That is not... "you've killed your messiah, now repent and get wet"/.
Be sure you notice this reader, as there are a lot of "Acts 2:38" false gospel people found on forums and in Pulpits, and in ROME... who dont care about the real Gospel.
Make sure you notice them... and avoid them.
