You didn't answer the questions I asked you.
Do you agree or disagree with the OP. Is repent & be baptized to receive the Holy Spirit the message for today's Body of Christ?
And would you be king enough to tell us when the Acts 8 convert received the H/s?
I'll try to address this reply after you address mine.
1st, I don't identify as Baptist. I joined in 2019 & my profile reads Non-Denom. Having said that, Baptist (whomever) have as much market on interpretation of Scripture here, as you do.
I believe scripture does cite (clearly & repeatedly) the change from the All Jewish repent & be baptized message. Starting with John the Baptist; baptism of repentance message, to Israel only! Was repent from running away, return to & prepare/purify/withb water (Jewish ritual) yourselves to meet the Lord your God. There is no mention of the Holy Spirit (except his encounter)
John is imprisoned & Jesus picks up the repent torch. His message is repent from running away from, return to God, because the kingdom of God is near. The OP explains this all Jewish kingdom message.
Did John or Jesus say, Repent be baptized (in his/my name) & receive the Holy Spirit? NO!
Enter (all the confusion) Peter Acts 2, read the text He is preaching to Jews only, during a mandatory (any male over 20 ys) trip to Jerusalem, MILLIONS are their for the required Pentecost feast.
Now, the Lord has died & rose. The Holy Spirit has indwelt the 120 (no mention of any of them being water baptized 1st) Peter tells the Jews listening, that Jesus was Messiah & has risen (I've seen & spoke with Him) They are sorry & say what can we do? He tells them you (in unbelief) allowed Him to be killed. Repent from unbelief to BELIEF. In the fact, He was our long promised (to our fathers) Messiah/Redeemer/Son of God.
For the Jew (of the time) this next part was like signing a death pact.
Acts 2:38 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.
1st listed of the 10: Thou shalt have no other gods before me. Jewish leadership (Priesthood) rejected Jesus, confessing Him as Lord was see as idolatry. Look what happened to Stephen & later Paul, & later every apostle except John.
Way to many NT believers cite Acts 2:38 as the litmus test for receiving the Holy Spirit/Eternal Life/Salvation. And promote water baptism as a requirement. My position is, THEIR WRONG!
I presented the 1st sighting of the (from at the time an ALL Jewish presentation) change (Acts 10) The OP cited these 2 verses (Eph 2:8, Rom 5:1-2) that speak directly to the change.
The following present the change as well & none of these cited verses require water 1st to receive the Holy Spirit
Under the NT gospel of the GRACE of God (Acts 20:24) Jew & Gentile receive FOREVER/ETERNAL LIFE GIVING HOLY SPIRIT BY FAITH. NO H2O required!
Justification/ETERNAL LIFE = indwelling Holy Spirit < Proof you're FOREVER SAVED > (Eph 1:13-14, 4:30, 2 Cor 1:22, 5:5, 2 Tim 1:14, Jn 14:16) comes/is accessed through Faith!
Rom 3:28 Therefore """we conclude that a man is JUSTIFIED by FAITH without the deeds of the law""".
Rom 5:1 Therefore being JUSTIFIED by FAITH, we have peace with God through our Lord Jesus Christ:
Rom 3:28 Therefore """we conclude that a man is JUSTIFIED by FAITH without the deeds of the law""".
Gal 3:24 Wherefore the law was our schoolmaster to bring us unto Christ, that we might be JUSTIFIED by FAITH.
Rom 3:30 Seeing it is one """God, which shall JUSTIFY the circumcision by FAITH, and uncircumcision through FAITH.
Rom 4:5 But to him that worketh not, but believeth on him that JUSTIFIETH the ungodly, his FAITH is counted for righteousness.
Gal 3:8 And the scripture, """foreseeing that God would JUSTIFY the heathen through FAITH""", preached before the gospel unto Abraham, saying, In thee shall all nations be blessed.
Gal 2:16 Knowing that a """MAN is NOT JUSTIFIED by the works of the law""", but by the FAITH of Jesus Christ, even we have believed in Jesus Christ, that we might be JUSTIFIED by the FAITH of Christ, and not by the works of the law: for by the works of the law shall no flesh be justified.
Faith is the conduit to ALL God's blessings!
Rom 3:25 """Whom God hath set forth to be a propitiation through FAITH in his blood""", to declare his righteousness for the remission of sins that are past, through the forbearance of God
Eph 1:13 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,
(MY NOTE: They HEARD, they BELIEVED the good news of Jesus sin atoning death & Jesus SEALED them with His ETERNAL LIFE giving Holy Spirit) No H2O required!
Eph 2:8 For by GRACE are ye SAVED through FAITH; and that not of yourselves: it is the GIFT of God:
(MY NOTE: By GRACE are you SAVED thru FAITH.) The GIFT you receive via FAITH is the LIVING WATER/CHRIST'/ETERNAL LIFE GIVING HOLY SPIRIT!
Rom 5:2 By whom also we have ACCESS by FAITH into this GRACE wherein we stand, and rejoice in hope of the glory of God.
(MY NOTE: we access God's GRACE/JSUS CHRIST/Titus 2:11 by FAITH). No H2O required!
Acts 15:9 And put no difference between us and them, """purifying their hearts by FAITH""".
(MY NOTE: It was God's GIFT of the HOLY SPIRIT that PURIFIED their hearts!) Not H2O
Rom 4:16 Therefore it is of FAITH, that it might be by GRACE; to the end the promise might be sure to all the seed; not to that only which is of the law, but to that also which is of the FAITH of Abraham; who is the father of us all,
(SIDE NOTE: The new covenant /testament is a partial fulfilment of God's unconditional promise to Abraham (Gen15). Cut 430 yrs (Gal 3:17) before before the Mosaic law covenant cut at Sinai. Scripture (more then once) declares Moses was a faithful servant over all God's house. Having said that, at the (Rev) marriage feast (the Lord hosts & serves at) it's Abraham sitting at the head of the table)
Gal 3:26 For ye are all the children of God by FAITH in Christ Jesus.
Acts 14:27 And when they were come, and had gathered the church together, they rehearsed all that God had done with them, and how """he had opened the door of FAITH unto the Gentiles""".
