By your logic, if there is no water available a person will die in their sins.You said that water baptism doesn't save anyone. Then why does Peter says, "baptism now saves you?' Peter knew we are saved by grace yet Peter can say baptism saves because that is how the grace that saves is given to us.
Jesus says. " he who believes AND is baptized will be saved" . Jesus could have said he who believes is saved and "then" is baptized but He didn't. You are the one saying that.
The idea that baptism is a symbol is arguing from silence and conjecture.
The Trinity is important yet the apostles never mention it. Does that mean it isn't true? That's the Mormon's and Oneness Pentecostal argument against it. You can't just blow off Tradition. Nowhere does the bible say not to hold on to what was passed down after the first century. That seems important. Why didn't they mention that?
The Jews would have been outraged had their children not been allowed to be baptized. Romans 6:5 says we are united to Christ in baptism. In Galatians 3:27 he says we have been baptized into Christ. To deny Jewish infants the right to be baptized into their Messiah would have cause a mass exodus from Christianity.
No, Peter does not say that water baptism saves. The baptism of the Spirit, which happens at regeneration, is evidence of salvation. Water is irrelevant to salvation.
