Of course if you believe salvation takes place at water baptism, then that's what you will believe regardless.
Rom. 6:3-4
"Know ye not, that so many of us as were baptized into Jesus Christ were baptized into his death?
Therefore we are buried with him by baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life."
Notice that Paul said, "baptized into Christ" and then "baptized into his death."
This is immersion into Christ, the death of Christ spiritually, not in water! Water baptism is the symbol of this spiritual immersion into the death of Christ. Peter even tells us it is the symbol.
1 Peter 3;21
"The like figure whereunto even baptism doth also now save us (not the putting away of the filth of the flesh, but the answer of a good conscience toward God,) by the resurrection of Jesus Christ:"
The "like figure" means a "symbol" it is the symbol of our spiritual baptism/immersion into the death of Christ.
I could go back to the OP and show you again in Col. 2 that this is an operation of God, the circumcision made without hands, but I doubt you want to hear it. Simply put, our salvation takes place spiritually in the heart through faith, not in the symbol of water baptism.
