36:13 Satan's craft is most successfully used against those who are depressed. When discouragement threatens to overwhelm the minister, let him spread out before God his necessities. It was when the heavens were as brass over Paul that he trusted most fully in God. More than most men, he knew the meaning of affliction; but listen to his triumphant cry as, beset by temptation and conflict, his feet press heavenward: "Our light affliction, which is but for a moment, worketh for us a far more exceeding and eternal weight of glory; while we look not at the things which are seen, but at the things which are not seen." 2 Corinthians 4:17, 18. Paul's eyes were ever fastened on the unseen and eternal. Realizing that he was fighting against supernatural powers, he placed this dependence on God, and in this lay his strength. It is by seeing Him who is invisible that strength and vigor of soul are gained and the power of earth over mind and character is broken.
