Just keep on ignoring Acts 2:39...
Please stop making up lies. I HAVE dealt with that verse and I've explained it to you multiple times.
You think that you understand these verses in your assertion that the promise in question was given only to those who saw Jesus' miracles.
That is the FACT, which you aren't interested it.
But Acts 2:39 is clear that there were those who were afar off who would be recipients of that promise...
There were Gentiles in that crowd, no doubt.
If Acts 2:38 applies to the entire human race, Paul's answer to the jailer couldn't possibly be accurate or true. Nonsense.
And even if that is referring to Gentiles, as you purport, I think that you need to realize that Cornelius and friends (and other Gentiles who would recreive baptism in Jesus' Name later) were not among those who originally saw Jesus perform His miracles.
Because Acts 2:38 didn't apply to them. They heard the gospel from Peter, believed it.
Acts 11-
13 He told us how he had seen an angel appear in his house and say, ‘Send to Joppa for Simon who is called Peter.
14
He will bring you a message through which you and all your household will be saved.’
15 “As I began to speak, the Holy Spirit came on them as he had come on us at the beginning.
16 Then I remembered what the Lord had said: ‘
John baptized with water, but you will be baptized with the Holy Spirit.’
17
So if God gave them the same gift he gave us who believed in the Lord Jesus Christ, who was I to think that I could stand in God’s way?”
v.13 is Peter's narrative of what Cornelius told him. v.14 is the result of believing the message that Peter brought to them. v.16 shows CLEARLY the difference between water and the Holy Spirit. They are DIFFERENT baptisms.
And v.17 clearly shows HOW they received the Holy Spirit; "believed in the Lord Jesus Christ". This is the exact same message Paul answered the jailer. NO WATER INVOLVED. But your eyes remain closed to truth.
Paul wasn't sent to baptize, that is true
And that refutes your whole theory.
