Because we are sinful by nature, we have developed sinful patterns, which we call habits. Discipline is required to break any habit. If a boy has developed the wrong style of swinging a baseball bat, he cannot just decide to change instantly. He has developed a certain habit, and much discipline – much correction and training – is required to break that bad habit and develop a new one. In the same way, our patterns of disobedience to God have been developed over a number of years and are not broken easily or without discipline. Discipline does not mean gritting your teeth and saying, “I’ll not do that anymore.” Rather, discipline means structured, planned training. Just as you need a plan for regular Bible reading or study, so you need a plan for applying the Word to your life.
