You are correct, there is no mention of baptism in these verses. But let me ask you, are these passages more "Scripture" than Acts 2:38? or Col 2:11-12? or Rom 6:1-4? NO! All these passages are equally Scripture; equally breathed out by the Holy Spirit. Which means that to take one of them as more important, more meaningful, more indicative of what we must do than the other is to disregard the Holy Spirit and ignore part of His command for our salvation.
That is not what Acts 22:16, Eph 5:26-27, Gal 3:26-27, and 1 Pet 3:21 say. It is not the believing or repenting that puts us into Christ, washes away our sins, and regenerates us with new life; it is baptism that does these things.
There is no division between repentance and baptism in Acts 2:38. The Holy Spirit through Paul is not saying to repent so you can be forgiven and then be baptized to show that you were forgiven. No, repentance and baptism are both included in what the Holy Spirit says brings about forgiveness.
Again, in Acts 22:16, it's "calling on His name" that washed away Saul's sins, not being baptized - which, by the way, Saul had already done (called on His name) before Ananias came to him. You don't think that during those three days before Ananias came to him, that he was calling on the name of Jesus? Of course he was! Jesus had already told him who he was persecuting, and the Lord told Ananias that Saul "is praying" in Acts 9:11. Who was Saul praying to? You and I both know that He was praying to Jesus, the ONE who he was persecuting. I'll say it again, Ananias called him BROTHER SAUL. Believers don't address non-believers as "BROTHER". Saul had already become a believer, he already had his sins forgiven, he was already born again.
Ephesians 5:26-27 This has NOTHING to do with the NEW BIRTH or WATER BAPTISM. It specifically speaks of the sanctification process for people who are ALREADY believers, speaking symbolically of how cleansing and the "washing of water WITH THE WORD" takes place.
Galatians 3:26-27 Once again, this is NOT speaking of water baptism. It's talking about the NEW BIRTH in the same way Paul speaks of it in 1 Corinthians 12:13 "For by one Spirit we were all baptized into one body, ... " Water baptism is one MAN baptizing another man. Being born again is a supernatural event where the HOLY SPIRIT baptizes us into the body of Christ. Later, a MAN baptizes us in water as a "picture" of what happened in the Spirit.
1 Peter 3:21 Peter is telling us that we are saved, not by the physical ceremony of water baptism, but by "the answer of a good conscience toward God." When we are born again, we take on a good conscience, because our sins are forgiven. Then in obedience to Christ, we "answer" what the Holy Spirit did in our hearts, by becoming baptized in water. Water cannot save us, but the Holy Spirit can.
Granted, the wording does make it sound like water baptism saves, but we know from all the other verses on water baptism, of which I will list a few more, that that is not the correct interpretation, and that Peter is not contradicting the entire group of verses on the subject.
Water baptism is essential for obedience, but it is NOT essential for salvation.
Jesus made it abundantly clear what is essential for salvation - and water baptism is not on the list:
John 3:14-15 "As Moses lifted up the serpent in the wilderness, even so must the Son of Man be lifted up; so that WHOEVER BELIEVES WILL IN HIM HAVE ETERNAL LIFE." No mention of water baptism here, and Jesus' disciples DID baptize in water.
John 3:16 "For God so loved the world, that He gave His only begotten Son, THAT WHOEVER BELIEVES IN HIM shall not perish, but have ETERNAL LIFE. No mention of water baptism here.
John 3:18 "He who believes in Him is not judged; ... " No mention of water baptism here.
John 7:38 "He who believes in Me, as the Scripture said, 'From his innermost being will flow rivers of living water." No mention of water baptism.
John 8:51 "If anyone keeps My word he will never see death." No mention of water baptism here, and Jesus' disciples DID baptize in water.
John 10:9 "I am the door; if anyone enters through Me, he will be saved, and will go in and out and find pasture." No mention of water baptism.
John 11:25-26 "I am the resurrection and the life; he who believes in Me will live even if he dies, and everyone who lives and believes in Me will never die." No mention of water baptism here.
And the list of verses goes on and on and on WITHOUT JESUS REQUIRING WATER BAPTISM.
