And when the servant of the man of God was risen early, and gone forth, behold, an host compassed the city both with horses and chariots. And his servant said unto him, Alas, my master! how shall we do?.. And Elisha prayed, and said, Lord, I pray Thee, open his eyes, that he may see. And the Lord opened the eyes of the young man, and he saw: and behold, the mountain was full of horses and chariots of fire round about Elisha. – 2 Kings 6:15,17

The young man was at that time in the peculiar condition of seeing, and yet not seeing. He saw the enemy surrounding the city, but not the greater host of the Lord’s angels who protected the man of God. Looking over the little walls of Dothan, he observed all the country round about to be occupied by the horses and chariots of the king of Syria; and he cried, “Alas, my master! how shall we do?” He could see the danger, but he could not see the deliverance; and therefore, the prophet lifted up his heart to heaven, and said, “O Lord, I pray Thee, open his eyes, that he may see!” Elisha reckons his servant’s natural sight as not seeing and regards the vision which detects the invisible as the only true sight. Perhaps I am addressing some, at this time, who are very friendly to the cause of God, and are even connected with it by relationship or occupation; they cheerfully lend a hand at any time in holy service so far as they can, and they wish prosperity to the cause of true religion. Yet their eyes have not been opened to see spiritual things; or, at least, not sufficiently opened to see the gracious and divine side of them. They see enough to perceive that they are in danger from a great enemy. They perceive that it is no easy thing to fight the battle of life: in the prospect of it they cry, “How shall we do?” They perceive that it is a difficult thing for a man to stand up for holiness, for truth, for integrity, for purity, and to maintain a gracious character throughout the whole of life. They seem to themselves to be environed with opposing forces in their business, in their temperament, in their companionships, and perhaps in their families. As for the cause of godliness, it seems hemmed in by adversaries; and they ask-What is to be done? Is not the matter desperate? Might it not be as well to surrender at once? For any such timid one I would present to God the prayer of Elisha: “O Lord, I pray Thee, open his eyes, that he may see!” ~ C.H. Spurgeon
