The Covenant and the Children of Believers

One of the distinctive doctrines that I love about Presbyterianism is what is called "covenant succession," the belief that the children of believers are claimed by God and set apart from the children of unbelievers. 

There are a number of Bible verses that describe this special relationship. 

In the Old Testament, God chastised Israel for sacrificing their children to idols: "You took your sons and your daughters, whom you had borne to me, and these you sacrificed to them to be devoured" (Ezekiel 16:20). As horrific as human sacrifice is, under any circumstances, Israel had compounded their sin by sacrificing the children that God claimed for Himself by covenant.

In that covenant, God had promised a blessing to His children: "And the LORD your God will circumcise your heart and the heart of your offspring, so that you will love the LORD your God with all your heart and with all your soul, that you may live." (Deuteronomy 30:6). The same promise is repeated in Isaiah 54:13: "All your children shall be taught by the LORD, and great shall be the peace of your children." And again in the New Testament: "The promise is for you and for your children and for all who are far off, everyone whom the Lord our God calls to Himself" (Acts 2:39).

It is important to understand that these promises are covenantal. The children of believers are placed in the visible church. It is not an absolute promise that the children of believers will themselves be believers. We know this from experience. We also have the explicit statement of God to Abraham: "Abraham said to God, 'Oh, that Ishmael might live before You!' God said, 'No, but Sarah your wife shall bear you a son, and you shall call his name Isaac. I will establish My covenant with him as an everlasting covenant for his offspring after him. As for Ishmael, I have heard you; behold, I have blessed him and will make him fruitful, and multiply him greatly'" (Genesis 17:18-20). Abraham had a son by his servant Hagar, Ishmael, and begged God to grant him salvation. Yet, God explicitly refuses, promising material blessings, but not eternal life. The distinction would be made again with Isaac's sons, Esau and Jacob. The Apostle Paul would use their example to illustrate God's sovereignty in grace (Romans 9:6-13). He applies the principle to the children of Christians in I Corinthians 7:14: "For the unbelieving husband is made holy because of his wife, and the unbelieving wife is made holy because of her husband. Otherwise your children would be unclean, but, as it is, they are holy." That is, federally holy, not personally holy.

While it isn't my topic here, this is the basis for infant baptism, just as it was the basis for the circumcision of Israel's children.
