All of the verses you shared are HIS word, love it.
BUT what do you do with these verses? What do you do with them?
JESUS said we need to be born of water and of spirit.
John 3:5 Jesus answered, Verily, verily, I say unto thee, Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God.
Speaking of the future.
Matthew 24:14 And this gospel of the kingdom shall be preached in all the world for a witness unto all nations; and then shall the end come.
This is the message spoken of in Matthew 24:14.
Acts 2:38-39
38 Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost.
39 For the promise is unto you, and to your children, and to all that are afar off, even as many as the Lord our God shall call.
Born of water in John 3..
Nicodemus is talking about the amniotic fluid of the womb.. water of the womb. Eg.. Can a man be born a second time into his mother's womb?
So Jesus doesn't say..this is not the water of birth I'm talking about.. but says to be born of water and of the Spirit.
He didn't contradict Nicodemus but added being born of the Spirit.
So John 3 isn't about water baptism.
Or the other way to look at John 3 is that it's the figurative washing of the Holy Spirit at salvation. Water representing the washing of the Word ..not water baptism.
Then Acts 2:38-39 must harmonize with other scripture. So the book of John barely mentions water baptism..neither does Romans 10.. neither does Ephesians 2.
So then the passage itself is about being baptised 'because of already having' remission of sins.
'For' the remission of sins..is like being given a pill 'for' and illness.
The illness is already there.
Salvation is already given.
Water baptism is the right response to having salvation..but not the means to get salvation.
The other way to look at it..is since baptism signifies a life long commitment to Jesus.. showing Jesus's life death and resurrection....
Is that it is 'for the remission of sin'.
Not salvation itself.. but representative of it.
