Both water and Spirit baptism are parts of one whole; the NT rebirth. (Acts 2:38-41, 8:12-18, 9:17-18, 10:43-48, 19:1-6, 22:16)
This is a misunderstanding. Water baptism symbolizes baptism of the Holy Spirit. 1 Pet 3:21
Failing to acknowledge the difference between the two always leads to a false doctrine about baptism.
1 Tim 1:16 - But for that very reason I was shown mercy so that in me, the worst of sinners, Christ Jesus might display his immense patience as an example
for those who would believe in him and receive eternal life.
The pattern throughout the NT is to believe an receive. It ryhmes, even.
If water baptism were required for salvation, it would ALWAYS be included. In fact, the VAST majority of verses regarding salvation/eternal life have NO MENTION of water baptism at all.
Those who believe in Christ receive eternal life. John 5:24.
“Very truly I tell you, whoever hears my word and believes him who sent me has eternal life and will not be judged but has crossed over from death to life."
That is salvation. No water required. And salvation involves the baptism of the Holy Spirit. Eph 1:13
"And you also were included in Christ when you heard the message of truth, the gospel of your salvation. When you believed, you were marked in him with a seal, the promised Holy Spirit,"
From the MOMENT of belief in Christ as Savior, the believer receives the Holy Spirit, IS saved and SHALL NEVER PERISH. John 10:28
"I give them eternal life, and they shall never perish; no one will snatch them out of my hand."
Demanding water baptism and faith in Christ for salvation is just like the Judaizers demanding circumcision for salvation.
Acts 15-
1 Certain people came down from Judea to Antioch and were teaching the believers: “Unless you are circumcised, according to the custom taught by Moses, you cannot be saved.”
2 This brought Paul and Barnabas into sharp dispute and debate with them. So Paul and Barnabas were appointed, along with some other believers, to go up to Jerusalem to see the apostles and elders about this question.
3 The church sent them on their way, and as they traveled through Phoenicia and Samaria, they told how the Gentiles had been converted. This news made all the believers very glad.
4 When they came to Jerusalem, they were welcomed by the church and the apostles and elders, to whom they reported everything God had done through them.
5 Then some of the believers who belonged to the party of the Pharisees stood up and said, “The Gentiles must be circumcised and required to keep the law of Moses.”
6 The apostles and elders met to consider this question.
7 After much discussion, Peter got up and addressed them: “Brothers, you know that some time ago God made a choice among you that the Gentiles might hear from my lips the message of the gospel and believe.
The blue words in v.1-2 are no different than this debate here on this thread. Except instead of circumcision, today it is water baptism.
The conclusion?
8 God, who knows the heart, showed that he accepted them by giving the Holy Spirit to them, just as he did to us.
9 He did not discriminate between us and them, for
he purified their hearts by faith.
This verse PROVES that water isn't required.
10 Now then, why do you try to test God by putting on the necks of Gentiles a yoke that neither we nor our ancestors have been able to bear?
11 No! We believe it is through the grace of our Lord Jesus that we are saved, just as they are.”
