Psalms 18:29

For by thee I have run through a troop; and by my God have I leaped over a wall.

By divine help the speaker can run through a troop and leap over a wall, because God imparts strength to break through obstacles and to prevail against opposing forces. That strength is bestowed on the afflicted, lifting them beyond their own natural power into victory. What could not be accomplished by human ability alone becomes possible when God supplies the needed force.

This overcoming power belongs to a wider testimony that God enlightens darkness for those who call on Him. He shields all who place their trust in Him, keeping them safe amid danger. Thus guarded and enlightened, they are enabled to advance securely and without being stopped.
