One of the secrets of the Kingdom life is to work diligently on our hearts and inner life. During this talk at our retreat in Pennsylvania, David Bercot makes the case that a strong devotional life is the key to living a strong Kingdom life. With humor and candor, David shares lessons from his own prayer and devotional life, giving many practicals to help us develop our inner lives as individuals and families.
See this attached list of devotional classics referred to in this lesson to supplement your devotional times with God.
