You can ask your smart phone questions or directions or consult your computer for answers on this or that, but only God s Word offers wisdom for this life and for eternity. Following on the heels of Greg Laurie s first Essentials book, this second volume delves into the nature of God, the essence of our salvation in Christ, and the mystery of faith. The book wraps up by offering practical counsel for understanding the will of God, for grappling with the demands of discipleship, and for fighting a successful battle against our enemy, the devil.
