Using the rod in anger results in rebellious children. Using the rod as God intended as a part of a child's consistent training results in secure, loving, and obedient children. When a child intentionally does something he knows he should not do, it may be time for the rod. But first you calmly go over with him what he did wrong, show the applicable verses about that type of behavior, and explain that God instructs parents to discipline children for that type of behavior. After the spanking and after he is done crying, you let him know how much you love him, and with him on your lap, pray with or for him.
Most people think of spanking as angrily whacking the child.
God's way is nothing like that. Now, when government laws do not oppose God's laws, we are to obey our earthly authorities, and indeed, we should be model citizens. I am in need of advice. We need to purchase a microscope for child-initiated discovery. Do you know of any children's story books, cartoons, etc.
