That means that you must first of all study the Bible for yourself. Then I recommend that you establish a regular time of family worship. But input from the Bible must not be limited to family devotions. Your children must learn that you are the head of your home and that God is the head over all. Another practical way in which we are to lead in the home is in the area of disciplining our children.
Scriptural discipline is the missing ingredient in so many homes today.
You only have to observe the behavior of the children to find out who is doing a good job and who isn't in this area. We take our cue here from the example of our heavenly Father. God disciplines His children because He loves them. It takes time, energy, and patience to discipline properly. Often I know that I don't feel like doing it - it is unpleasant.
