God gives promises and practices to Christians to bring up their children in the faith because He loves us. We are called to believe what God says and then to act on that belief, which Scripture describes as “the obedience of faith”. Think of Noah building a boat in the middle of nowhere. Think of Abraham leaving Haran and Sarah going along with him. Think of Rahab hiding the spies. These are acts of faith in the life every parent who must trust God to work in the life of his and her child and use us as His instruments.
