E.g., Leviticus 19:45: “I am the LORD who brought you up out of Egypt to be your God; therefore be holy, because I am holy.”
God’s moral law arises out of his character. Our moral capacity has great implications for the family relationship: I can choose how to interact with my wife—am I going to beat her or am I going to go and have an affair?—and I can choose how to interact with my wife—am I going to teach them to be moral and am I going to use spanking out of anger rather than a teaching method?
We also know that God has great cognitive ability. E.g., “The foolishness of God is wiser than man’s wisdom, and the weakness of God is stronger than man’s strength” (1 Cor 1:25).
If God and man neither had cognitive abilities, how could God place his moral law in a written form so that man could understand that law? Man’s cognitive abilities also have an impact on marriage: we are in this course to learn how to be better husbands, wives, and parents. If we did not have cognitive ability, we couldn’t do that. Partners often need to retrain the way they think about their spouses. Without cognitive ability that would be impossible.
