He who spares his rod hates his son, but he who loves him disciplines him promptly. (Proverbs 13:24, NKJV)
Many of us have been on an airplane and witnessed an unruly child. Undisciplined and out of control, the child disrupts the entire cabin with screaming or other displays of defiance. This reminds us that discipline is a combination of instruction and correction. One cannot expect a child to behave who has not been taught acceptable behavior. The “rod” of correction comes after the instruction, and only when the instruction is not accepted. In order to be effective, corrective discipline needs to be “promptly” applied. Failure to do so invites even more resistance. The rod of correction is not a rod of abuse; they are two very different things. As God disciplines His children in love, and sets an example for parents to follow. “Now no chastening seems to be joyful for the present, but painful; nevertheless, afterward it yields the peaceable fruit of righteousness to those who have been trained by it” (Heb. 12:11).
