" Double-mindedness only leads to spiritual instability, and those who love money can make no progress in the Christian life. No matter how often they attend church or study orthodox theology, they remain “destitute of the life, power, and comfort of religion, so long as they cleave to those things which are incompatible with it.”13 Gospel simplicity dies by split motives. Befriending the world and befriending God is impossible (James 4:1–10). You cannot have both a love of drunkenness and a desire for health. Split desires and split motives lead to sickness, decay, and death. Spiritual health is gained—and maintained—only by singular motives. "
