Infant baptism focuses on the "sovereign grace of God." This means that by faith you submit to and rely on the sovereign grace of God for your infant’s future salvation. You also as parents take a vow, along with the congregation as the extended family of God, to take direct responsibility for the Christian training of your child. In so doing, we acknowledge that long before we sought the Father’s forgiveness or even knew of our need, God did all that was required for our salvation. Baptizing your infant does not "save" him or her, but rather, it is a tangible way to seek and rely on God’s grace that "prevenes”¾runs ahead¾preparing the way and making possible your child’s future approach to God. (Traditionally, baptism requires that both parents be Christians. However, baptism is also appropriate for the children of one parent when Christian sponsors stand with and take vows with the parent.)
We are bold to claim that God’s grace is always at work in the life of one baptized early. This is why baptism is administered only once for each person. Hence, “no more water" will be necessary when a baptized infant comes to a mature age¾the water applied on the infant will still be effective and efficacious because God's sovereign grace transcends any human merit or time. Although rebaptism is not appropriate, there will be a time for “confirmation” for those who were baptized as infants.
