Our endurance does not depend on favorable circumstances. We can strengthen our endurance by relying on Jehovah. (Rom. 12:12) Jesus’ promise in today’s text means that we must remain faithful despite any challenges we face. By enduring each trial now, we can become stronger before the outbreak of the great tribulation. As with endurance, true courage comes from relying on Jehovah. How can we strengthen our reliance on him? By reading his Word every day and meditating on how Jehovah saved his people in the past. (Ps. 68:20; 2 Pet. 2:9) When the nations attack us during the great tribulation, we will need to be courageous and to trust in Jehovah as never before. (Ps. 112:7, 8; Heb. 13:6) If we rely on Jehovah now, we will have the courage we need to face Gog’s attack. We are convinced that we can remain ever safe under Jehovah’s loving protection.​—1 Cor. 13:8. w19.10 18 ¶15-16
