Water baptism is an outward expression of one's inner spiritual transformation. Necessary for further spiritual growth.
Water Baptism is the gateway to discipleship, not the ticket to heaven. Their ticket to heaven was punched in Acts 10:44. When they were BAPTIZED via Christ's salvation SEALNG (Eph 1:13-14, 4:30, 2 Cor 1:22, 5:5, 2 Tim 1:14) eternal life giving Holy Spirit! > No Water & no HANDS (Col 2:11 also see 1 Cor 12:13) are needed.
Water Baptism is necessary for spiritual growth, not spiritual birth. Water Baptism is the first step of discipleship, not the first breath of one's new spiritual life/birth.
I would agree that WB is good for spiritual growth, although to say it is necessary sounds like it is salvific, which is not what the NT teaches. Jesus taught that his righteousness (Matt. 5:10&20) surpassed and superseded that of those who obeyed and taught the law (cf. Matt. 12:5-12, 19:3-9, Heb. 7:18-10:1). The law is represented by John the Baptist in Matt. 3:11a, “I baptize you with water [WB] for repentance” [forgiveness of sins indicated in the Torah, cf. Rom. 7:4-8:17], and Spirit baptism (SB) is indicated in Matt. 3:11b, “but after me will come one who is more powerful than I, whose sandals I am not fit to carry. He will baptize you with the Holy Spirit and with fire.”
However, some people (“Actsists”) focus on events in Acts such as WB and glossolalia rather than on teachings in the epistles about faith/SB being what is essential (“Faithists”). The book of Acts does not teach foundational Christian doctrine but merely records what occurred during the early days of the church era as the revelation of GRFS transitioned from OT beliefs to the NT doctrine that is taught in the epistles, which never command WB or tongues as signs of SB or as essential for salvation.
The transition can be seen as occurring in Acts 16:31-34, where Paul told the jailer to believe in the Lord Jesus in order to be saved, NOT to believe and be WB in order to be saved. However, the jailer and others in his family who believed in God were WB. Then in Acts 17:30-34 Paul told the Athenians to repent, which some did, but whether they were WB is not mentioned. Then in Acts 19:1-6 Paul encountered some disciples of John who had been WB but had not been taught about SB, so they received SB when Paul placed his hands on them. Then in Acts 26:16-18, when Paul recounted his calling to King Agrippa, he quoted Jesus as saying, “I am sending you to open their eyes and turn them from darkness to light, and from the power of Satan to God, so that they may receive forgiveness of sins and a place among those who are sanctified by faith in me.” WB was not mentioned, which continued to be the case in Paul’s epistles.
The foundation cited in 1Corinthisans 3:11 is Christ, referring to faith in Christ’s atonement (Rom. 3:12-5:1). Instructions about baptisms are mentioned in Hebrews 6:2, which logically, semantically, and mathematically had to be that WB is a sign or rite portraying a soul has been SB (Col. 2:12), since there is only one baptism (Eph. 4:5) into one body (Eph. 4:4, 1Cor. 12:13). This understanding was held by Christians generally until RC perverted it by practicing infant sprinkling, which was corrected by the Anabaptists during the Protestant Reformation.
By the last of Paul’s epistles, WB came to be understood as a good but non-essential work or rite, like physical circumcision, and the basis for believing folks are filled with the HS is reflecting God’s love for everyone (Matt. 22:37-40, 1John 4:7-21, John 13:35, Rom. 5:5, Gal. 5:6 & 22, etc.). Then, like now, the rite is performed as an apt way of portraying saving faith in the atonement of Christ, even though the work is not required, just as physical circumcision was not required for salvation either (per Paul in Romans 3:21-5:1).
WB replaced physical circumcision in the NT church per Col. 2:11-12, which says, “In Christ you were also circumcised, in the putting off of the sinful nature, not with a circumcision done by the hands of men but with the circumcision done by Christ, having been buried with him in baptism and raised with him through your faith in the power of God, who raised him from the dead.” Surely Paul
did not mean to suggest that baptism done by the hands of men is salvific!
