Infants and children are born with sin (Ps 51:5), so they also need to be born again. The promise of baptism for the remission of sins is also given to the children (Acts 2:38-39). Children were never excluded from God’s covenant with his people (Gen 17:9-14). Therefore, we must not forbid children from receiving salvation since the Lord Jesus Himself does not reject little children (see Lk 18:15-17).

We can also see that in the early church, entire households were baptized (Acts 16:15, 32-34; 18:8; 1Cor 1:16). In the Old Testament, the entire household, including children and infants, crossed the Red Sea (Ex 10:9-10, 24; 12:31). Children and infants were not left in the land of bondage. Crossing the Red Sea prefigures the New Testament baptism (1Cor 10:1-2). So in the same way, children and infants must also be baptized to be cleanse of their sins and be released from the bondage of Satan.

Children were healed of their diseases through their parents’ faith (Mt 15:28). By the same token, children and infants may be baptized based on the faith of their parents (Jn 4:49-51). We must also keep in mind, however, that it is the grace of God and the cross of Christ, not the conscious choice of humans, that gives baptism its effect. So even if children cannot make a conscious choice to receive God’s grace, they should not be excluded from God’s grace.
