Being "born of" something is not the same thing as being "immersed in" something.
Being 'born again' is 'spiritual'.
Being 'baptized' in water is 'physical'.
The two do not mix.
Related - yes. Same thing - no.
In 1 Corinthians 12:13, the word 'baptized' - meaning 'immersed' - is referring to our inclusion / insertion / integration into the body of Christ.
Even then, that itself is not 'born of' or 'born again' - it is a kind of aftermath / outcome / result of being born-again.
Being 'born again' is one thing only - receiving the Holy Spirit of God - being 'indwelt' by the Holy Spirit.
These 4 things are different:
1) indwelling of the HS
2) baptism by the HS
3) baptism of the HS
4) filled with the HS
#1 & #2 are very closely associated.
#2 is a direct result of #1 - but, is not [identically] the same thing.
What the verse is saying is that - by-and-because-of the Holy Spirit (indwelling us) - we are all made a part of the body of Christ.
In-of-itself, [this verse] has absolutely nothing [directly] to do with water baptism.
the apostles must not have known that water baptism was irrelevant
While Peter yet spake these words,
the Holy Ghost fell on all them which heard the word. …..
Can any man forbid water, that these should not be baptized, which have received the Holy Ghost as well as we?
….And
he commanded them to be baptized in the name of the Lord. Then prayed they him to tarry certain days.”
Acts 10:44, 47-48
To have faith we need hear something and believe it then we have a reason to act on it. like this
“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. And with many other words did he testify and exhort, saying, Save yourselves from this untoward generation.
Then
they that gladly received his word were baptized: and the same day there were added unto them about three thousand souls.”
Acts 2:38, 40-41
if we reject it and explain why it doesn’t apply it’s because we don’t believe it is true. Look at this fellow he was a believer
“Then Philip opened his mouth, and began at the same scripture, and
preached unto him Jesus.
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?
And Philip said,
If thou believest with all thine heart, thou mayest. And he answered and said,
I believe that Jesus Christ is the Son of God.
And he commanded the chariot to stand still: and
they went down both into the water, both Philip and the eunuch; and he baptized him.”
Acts 8:35-38 KJV
it seems like either the Bible is teaching irrelevant doctrine that we should reject or we should believe it and get baptized for the remission of sins in christs name through his death for our sins
“Know ye not, that
so many of us as were baptized into Jesus Christ were baptized into his death? 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.
knowing this, that our old man is crucified with him, that the body of sin might be destroyed, that henceforth we should not serve sin.”
Romans 6:3-4, 6 KJV
Receiving the holy spirit is a gift given by Jesus it’s what he promised them . Water baptism is what God said to do in christs name and he would remit our sins because
we’re acting on his promise to do so ( faith )
there’s a relationship for certain we need to receive the holy
spirit and get
baptized in
water for remission of sins in his name
“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.”
John 3:5 KJV
