I would have lost heart, unless I had believed that I would see the goodness of the Lord in the land of the living (Psalm 27:13, NKJV).
Discouragement is a tool our adversary, the devil, uses against us. The encroachment of spiritual foes wears us down unless our faith remains focused on the Lord Jesus (Heb. 12:1-2; 2 Cor. 4:16-18). Worldliness in the church, false doctrine threatening and deceiving hearts, apathetic negligence of spiritual duties, derelict fathers, careless mothers, disobedient children, and the moral decline of our nation are just some of the things that cause Christians to lose heart. David faced enemies who sought his life, yet he was confident in the Lord’s strength and salvation (Ps. 27:1-3). He waited on the Lord with faith, and the Lord delivered him from his foes (Ps. 27:4-5, 14). Likewise, we face spiritual enemies intent on destroying our souls, but the Lord’s strength sustains us in our spiritual struggles (Eph. 6:10-13). We refuse to be discouraged because we believe the Lord’s goodness blesses us in “the land of the living” even as we anticipate eternal glory (Phil. 4:4-7). Encouraged by the faithfulness of the Lord, “let us not grow weary while doing good, for in due season we shall reap if we do not lose heart” (Gal. 6:9). So with David, let us “Wait on the Lord; Be of good courage, and He shall strengthen your heart; Wait, I say, on the Lord” (Ps. 27:14)!
