This quote comes from the lips of Elisha as he calmed his servant who was afraid of an enemy force that had surrounded the village where they were staying. The servant saw the enemy - Elisha saw the Lord and His army surrounding the enemy! This is the time when Elisha prayed that his servant's eyes would be open to see that the army of God was far more numerous than the army of men at their doorstep!
You know what our trouble is? We somehow can see our enemies easier than we can see the Lord! And you know why that seems to be so true? It's because we don't keep our eyes on the Lord regularly enough. When was the last time you took time to take a good long look at Jesus? You'll find Him in His Word and in prayer. And that won't happen just because you go to church on Sunday. You need daily contact with the Lord, or as the old hymn says, "I Need Thee Every Hour"!
Whether you're looking at the Lord or not, you're still surrounded by Him and His army! Never will you face a foe that is more powerful or more numerous than God's hosts of heaven. But you won't enjoy His presence if you keep your eyes on your troubles. "Turn your eyes upon Jesus" and do that often!
