I think that one of the most important portions of scripture regarding how every person is saved (we're all saved in the exact same way) is found in Eph 1..
In whom ye also trusted, after that ye heard the word of truth, the gospel of your salvation: in whom also after that ye believed, ye were sealed with that holy Spirit of promise, which is the earnest of our inheritance until the redemption of the purchased possession, unto the praise of his glory.
By faith we are saved and faith comes by hearing the word.. GOD ALONE can judge the heart so HE ALONE seals a person with the Holy Spirit after they believe.
Water baptism is for believers.. and believers have already had the baptism of the Holy Spirit... and that's what Paul writes in 1 Cor 12... that we are all baptized into that one body BY THE SAME SPIRIT.
There's only one baptism.. so you need to decide which one is necessary for salvation.. baptism with water AFTER a person believes, or the baptism into the body of Christ after a person believes..
IMO it's obvious.. and I think that it's a shame that multitudes of people are taught over and over again that they're born again (even if they're an infant) because some guy dipped them in water.
I agree with the statement.. how did we ever get to this place.. ?
I'll add by saying that of course a born again Christian should be baptized in water.. although they're already saved at that point.. and the importance of this is to also show the assembly that you're willing to identify yourself PUBLICLY with the death, burial, and resurrection of our Lord Jesus Christ.
1)baptism is the point where sins are remitted, Acts 2:38. I remained lost in my unremitted sins until I was water baptized and then in water baptism God did the work of cutting away (remitting) the body of sin, Col 2:12.
2) The Ephesians would have been baptized:
a)Eph 2:8 the Ephesians were saved through faith
EPh 2:8---faith>>>>>>>>>>>saved
2Pet3:21--baptism>>>>>>>>save
Only one way to be saved so thier fath must have included baptism.
b)in Eph 1:1-9 several times Paul says the Ephesians were spiritually located "in Him' or "in Christ". Gal 3:27 baptism is the only way to be in Christ for 'belief only' does not put one in Christ.
c)In Acts 19:5 some of the EPhesians were baptized in the name of the Lord which is the same baptism of Acts 2:38
d) the Ephesians would have been born again and were per Eph 5:26 cf Jn 3:5.
Eph 5:26----the word ++++++++++++washing of water>>>>>>>>cleansed
Jn 3:5-------spirit+++++++++++++++++water>>>>>>>>>>>>>>in the kingdom
The Ephesains washing of water references thier having been water baptized. Above you mentioned 1 Cor 12 where the Corinthians were born again, so we have:
Eph 5:26----the word ++++++++++++
washing of water>>>>>>>>cleansed
Jn 3:5-------spirit+++++++++++++++++
water>>>>>>>>>>>>>>in the kingdom
1Cor12:13---spirit++++++++++++++++
baptized>>>>>>>>>>>>>in the body
All three verses refer to being born again. Since "cleansed", 'in the kingdom' and 'in the body' are all equivalent, all refer to a save position. Since there is but only one way to be saved then all three verses MUST express the same idea. That means "washing of water", "water" and "baptized" all refer to water baptism.
There is one baptism in effect today, Eph 4:5 and that would be Christ's water baptism of the great commission, Mt 28:19,20, Mk 16:15,16; Lk 24:47 cf Acts 2:38.
