I have never been a fan of Calvinistic dogma. Of course each of us must answer for the behaviors we have done / do in this life, and the Bible tells us that by not choosing The Grace of God in Christ we have condemned ourselves for not believing God. I do not believe any Baptism remits sin, but the submitting and following through is an act of the will and when the will of one repents of sin, that is when the remitting happens and the baptism is an outward sign of same. When Jesus submitted to John’s Baptism there was not sin to remit. Jesus did it to fulfill all righteousness.
Jesus had no sins to remit but for the rest of that do, baptism is where that remittance, the washing away of sins takes place by the blood of Christ, Acts 2:38.
Christ shed His blood that washes away sin (Rev 1:5) in His death, (Jn 19:34).
We then must have access into the death of Christ where He shed His blood so it can wash away our sins.......
Rom 6:3-5 “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. For if we have been planted together in the likeness of his death, we shall be also in the likeness of his resurrection:”
Baptism is the only access into the death of Christ where His shed blood washes away sins.
