And what I say unto you I say unto all, Watch. – Mark 13:37

“Watch!” Oh, how little is done of this kind of work! We scarcely watch as we ought against the devil; but how little do we watch for the coming of our Master! Look for every sign of His appearing, and be ever listening for the sound of His chariot wheels. Keep the candle burning in the window, to let Him see that you are awake; keep the latch on the door, that when He cometh you may quickly open unto Him. Hopefully watch until the day break, and the shadows flee away.

I seem just now as though I were a soldier in this great guard-room, and as if we were sitting in these shadows, and perhaps in the darkness, and seemed very much dispirited; and I would say to you my comrades, “Come, brothers, let us cheer up. The Lord hath appeared to one and another of us. He hath given to some of us the light of His countenance, and He is coming back to welcome us all unto Himself. Let us not be dismayed; our glorious Leader forgets not the weakest and feeblest of us, neither is any part of the battle-field beyond the reach of the great Captain’s eye. He sees which way the struggle is going, and He has innumerable reserves, which He will bring up at the right time. I seem to hear the music of His horse’s hoofs even now. He is coming who shall turn the scale in the worst moment of the conflict, for the battle is the Lord’s, and He will deliver the enemy into our hand. Let no man’s heart fail him because of yonder Goliath; the God who has raised up men to slay the lion and the bear, will yet find a David and a smooth stone to kill this mighty giant. Wherefore, brothers, be of good courage.” ~ C.H. Spurgeon
