Confusion is the enemy of spiritual orientation. Rest, properly taken, gives clarity to the mind. Weariness by contrast, can make us seek gratification and energy from food or drugs, or from various illicit relationships, or from egoistic postures that are, in Paul’s words, “upon the earth.” They pull us away from reliance upon God and from living in his power
