““All behavior is linked to attitudes of the heart. Therefore, discipline must address attitudes of the heart. This understanding does marvelous things for discipline. It makes the heart the issue, not just the behavior. It focuses correction on deeper things than changed behavior. The profoundest issue is what happens in the heart. Your concern is to unmask your child’s sin, helping him to understand how it reflects a heart that has strayed. That leads to the cross of Christ. It underscores the need for a Savior. It provides opportunities to show the glories of God who sent his Son to change hearts and free people enslaved to sin.””
