Instruction, and advice, and commands will profit little, unless they are backed up by the pattern of your own life. Your children will never believe you are serious, and really wish them to obey you, so long as your actions contradict your instruction. One minister I know made a wise remark when he said, “To give children good instruction, and a bad example, is the same as pointing out to them the way to heaven, while we take them by the hand and lead them down the road to hell” (Tillotson).
