1. ) When your children do wrong, God has warned you, the parent, that not spanking them is a display of hatred towards them. It is as if you do not care nor love them. Proverbs 13:24. By not spanking, you convey to the child that sinning against God, and disobeying you the parent, is ok, it is acceptable; worse, you encourage such behavior to continue and grow in strength, all the while both child and you, the parent, are disobeying God’s Word.
2.) Your children are young, and are still capable of being molded to right behavior and godly respect of authority. Spanking them now will, by God’s grace, prevent an even greater punishment later on, perhaps by the laws of men and society. Proverbs 19:18. Spank their bottoms, while there is still hope.
3.) Children are born into this world with a natural inclination to sin continually. They are not sinless angels. The sin of the first Adam was imputed to them. Sin is foolish, yet apart from the grace of God and regeneration, an inescapable reality. Your child, apart from being born again will run and seek after the foolishness of sin. God tells us that the rod of discipline – not a quiet chair or some silly Dr. Spock idea – deters such a cute beast from seeking further crimes in the home and elsewhere, and establishes respect for his or her position in the family. Proverbs 22:15.
4. Spanking your child may hurt you to do so, but it will not kill them. Suck it up. It is in the best interest of your children –and you the parent – to wear their britches out when necessary. Better to suffer temporarily now under the hand of a loving parent, than to allow and encourage sin to grow and all barriers to hating God’s instruction to be dismissed. Proverbs 23:13.
5.) Spanking promotes wisdom in children. You, as a parent, want your children to be wise do you not? If you do not spank them, they will have no incentive, nor instruction on being wise. All sense of authority gone, they will continue to seek their natural rush towards sin alone, and you will be to blame as a result of disobedience to God’s Word. He instructs you to spank your children so to plant a seed of wisdom, to prevent them from their present course of disobedience. Worse, if you do not spank your children, they will bring shame to you as a parent. Unchecked by loving spanking, they will continue to do whatever they want, embarrassing you, shaming you, by acts that you did not fathom would come to pass in their earlier days. Proverbs 29:15, 16.
