As with the exodus, the cross is proof that God is real and powerful. He moved history in exactly the way he promised (see Isaiah 53). He raised Jesus from the dead! More than that, if he was willing to give his own Son for our good, we can trust that he is for us. He loves us. The objective evidence of his love is right there on the cross, and we can argue for the cross with objective evidence.

In a society that’s hostile towards Christian morality, how should we go about teaching our children God’s commands so that they’ll desire to follow him rather than the culture surrounding and pressuring them?

Not a God of Blind Faith

The first thing to remember is this: Our God is not a God of blind faith. As our Creator, he knows we are beings who need reasons for what we do, beings who are rational and who love, beings who are motivated by a desire to seek our good and the good of our loved ones. Of course, our sin distorts these qualities, even at the best of times, and we can be deceived about what actually is good for us (see Eve). But at root, our rationality and our desire to pursue what’s good for us are both good aspects of our humanity that God repeatedly appealed to when revealing his commands to his people.

We see a clear example of this approach in Deuteronomy 6:20–25, where God instructs the Israelites as to what they should emphasize when teaching their children his commands:

When your son asks you in time to come, saying, “What do the testimonies and the statutes and the judgments mean which the Lord our God commanded you?” then you shall say to your son, “We were slaves to Pharaoh in Egypt, and the Lord brought us from Egypt with a mighty hand. Moreover, the Lord showed great and distressing signs and wonders before our eyes against Egypt, Pharaoh and all his household; He brought us out from there in order to bring us in, to give us the land which He had sworn to our fathers. So the Lord commanded us to observe all these statutes, to fear the Lord our God for our good always and for our survival, as it is today. It will be righteousness for us if we are careful to observe all this commandment before the Lord our God, just as He commanded us.”
