God said the parent corrupts their children to the 3rd and 4th generation..
Why then would He then tell you to honor your parents?Ex 20:5 You shall not bow down to them or worship them; for I, the LORD your God, am a jealous God, punishing the children for the sin of the parents to the third and fourth generation of those who hate me
Is it because it is the ideal even when parent's fail? In honoring, the return to righteousness comes to the child's understanding.Ex 20:12 Honor your father and your mother, so that you may live long in the land the LORD your God is giving you.
