One of the great quotes on spiritual discipline is "Discipline without direction is drudgery." If you do not have direction in your spiritual discipline it will be painful work. For example, fasting without purpose is just dieting. One of the primary reasons we resist spiritual discipline is because of a lack of purposeful direction.
This sermon series is called Spiritual Disciplines. We want to equip our family with the importance of worship, prayer, and fasting. And not just the activities but also the attitude. The purpose of spiritual discipline according to the scriptures is "for godliness" (1 Timothy 4:7-8). Practicing discipline is designed to help disciples of Jesus to look more like our Savior. To sacrifice like Him! To depend upon the will of the Father like Him! To make disciples who make disciples like Him!
