1 Peter 3:21 says: “Baptism, which corresponds to this, now saves you, not as a removal of dirt from the body but as an appeal to God for a good conscience, through the resurrection of Jesus Christ,”
Thankfully, though, we don’t have to guess at what Peter means in this verse because he clarifies that for us with the phrase “not the removal of dirt from the flesh, but an appeal to God for a good conscience.” While Peter is connecting baptism with salvation, it is not the act of being baptized that he is referring to (not the removal of dirt from the flesh). Being immersed in water does nothing but wash away dirt.
What Peter is referring to is what baptism represents, which is what saves us (an appeal to God for a good conscience through the resurrection of Jesus Christ). In other words, Peter is simply connecting baptism with belief. It is not the getting-wet part that saves but is the “appeal to God for a clean conscience” which is signified by baptism, that saves us. The appeal to God always comes first. First belief and repentance, then we are baptized to publicly identify ourselves with Christ.
