The Bible clearly states that we do not inherit sin as children. In Ezekiel 18:20 we read, “The son shall not bear the iniquity of the father, neither shall the father bear the iniquity of the son.” This verse tells us that we are not responsible for any of our ancestors’ sins, even all the way back to Adam.
What is sin? In 1 John 3:4 we read “For sin is the transgression of the law." One has got to transgress God’s law before he can sin. This is how the Bible defines sin. Infants cannot transgress God’s law and thus have not sinned.
Infants are not suitable candidates for baptism, since they cannot believe. Our Lord says in Mark 16:16, "He who believes and is baptized will be saved." Here one of the prerequisites of being saved is to believe, which is impossible for an infant to do. In Acts 8:36-37 the question was asked, "'See here is water; what hinders me from being baptized? And Philip said, if you believe with all your heart you may.' Here again we see the condition that must be met before a person can be baptized is you must “believe with all your heart”. Can an infant do this? No. Also one of the prerequisites of being baptized is one must repent. The apostle Peter told a group of people to “Repent and be baptized every one of you in the name of Jesus Christ for the remission of your sins” (Acts 2:38). Can an infant repent? It would be absurd to think an infant could believe or repent, but it is just as absurd to think an innocent infant, who is without sin, must be baptized for the forgiveness of sins, which he does not have. In Acts 8:12 we read, “But when they believed Philip as he preached the things concerning the kingdom of God and the name of Jesus Christ, both men and women were baptized”. Notice it says “men and women were baptized”, not children.
Satan has many ways in fooling people into being lost. The lie that Satan tells here to people who have become accountable is that since you were baptized as an infant, you do not need to be baptized for the remission of your sins now that you have become accountable and responsible. Satan knows that infant baptism accomplishes nothing. He also knows, when people who were baptized as an infant become accountable, that at that time they are lost. Many souls of those who follow Satan will be lost. Satan has fooled people into baptizing their babies, giving them a false sense of security. Jesus says in Mark 16:16, “He that believes and is baptized shall be saved.”
