Exodus 20:4–6 (NKJV)
4 “You shall not make for yourself a carved image—any likeness of anything that is in heaven above, or that is in the earth beneath, or that is in the water under the earth; 5 you shall not bow down to them nor serve them. For I, the LORD your God, am a jealous God, visiting the iniquity of the fathers upon the children to the third and fourth generations of those who hate Me, 6 but showing mercy to thousands, to those who love Me and keep My commandments.
This morning we have the privilege of baptizing Carly Bryan. Permit me to say a few words before we do so.
Baptism says something about us and baptism says something about God. First, baptism says something about us. Baptism declares, in no uncertain terms, that we are sinners in need of salvation by Christ. And the baptism of infants announces the sober reality of original sin. Even this child, not yet old enough to know her right hand from her left, has been born in sin. By nature, she is a child of wrath, even as the rest. Christian parents don’t have magic sperm and eggs that prevent the transmission of corruption – would that it were so! Baptism reveals that we are sinners in need of salvation by Christ – only He can save us, we cannot save ourselves.
Second, baptism says something about God. It announces that God has graciously provided a way of salvation, a way to be cleansed of our sin, cleansed of our corruption – both the original sin with which we are born and the actual sin that we ourselves begin to practice. God has provided a sacrifice to cover the guilt of our sin in the Person of His Son, our Lord Jesus Christ. Baptism reveals God’s grace.
And the baptism of infants declares something further about God’s grace. The baptism of infants reveals something remarkable about God – His grace is not confined to atomistic individuals but extends itself from one generation to the next. In this baptism, God promises Carly that He will be her God and the God of her children after her – for He has been her parents’, grandparents’, and great-grandparents’ God before her. Notice our text today:
For I, the LORD your God, am a jealous God, visiting the iniquity of the fathers upon the children to the third and fourth generations of those who hate Me, 6 but showing mercy to thousands, to those who love Me and keep My commandments.

And so Mary, the mother of our Lord, sings in her Magnificat: “For God’s mercy is on those who fear Him from generation to generation” (Lk 1:50). Baptism reveals something about us – our sin; but it also reveals something about God – His abounding grace. And praise God for that!
