The act of baptism is something that one must look to the New Testament to figure out the purpose of it, and when one should be baptized. There is a common practice among denominations that “baptize” babies when they are very young. Some call it “christening,” some call it “baptism” whether they use sprinkling, pouring, or immersion. However, the Bible teaches only one mode of baptism, and it also teaches us the purpose of it, and when one should be baptized.
The purpose of baptism is set forth so clearly in the New Testament. It is “for the remission of sins” (Acts 2:38). Baptism places one “into Christ” (Gal. 3:27). Baptism “washes away sins” (Acts 22:16). Baptism “does also now save us” (I Pet. 3:20-21). Therefore, if baptism washes away sins, and is for the remission of sins, and saves us from our sins, then obviously one must have sin in order to be scripturally baptized. However, a baby, or even a young child does not have sin. They are not full of sin, and lost; they are not saved either; they are safe. For one to commit sin, he must know the difference between right and wrong. Sin is the transgression (overstepping) of God’s law (I John 3:4). Therefore, there is something that we call the “age of accountability.” Children are not accountable. The mentally challenged are not accountable for their actions. They don’t know the difference between what is good and what is evil. Isa. 7:16 speaks of a time “…before the child shall know to refuse the evil, and choose the good…”
I say all this to come to this point: if you were baptized as a child, did you know what you were doing? How old were you? Did you know what the difference between right and wrong was? Did you know that this baptism placed you into the church that Jesus built (I Cor. 12:13)? Did you know that you had sinned [if accountable], and this is why you were being baptized? Maybe you did, I don’t know; only you can answer these questions. However, if you have any doubt, I would strongly urge you to be baptized scripturally. For, if you did not know these things when you were a child at your baptism, then you really just got wet. Contemplate on it, and I’m confident that you will make the right choice. You just need to do what is best for your spiritual life, and what is going to get you in a right relationship with God.
