1 Thessalonians 5:6
Therefore let us not sleep, as do others; but let us watch and be sober.
When a man is asleep he is insensible. The world goes on, and he knows nought about it. The watchman calls beneath his window, and he sleeps on still. A fire is in a neighbouring street, his neighbour's house is burned to ashes, but he is asleep and knows it not. Persons are sick in the house, but he is not awakened; they may die, and he weeps not for them. A revolution may be raging in the streets of his city; a king may be losing his crown; but he that is asleep shares not in the turmoil of politics. A volcano may burst somewhere near him, and he may be in imminent peril; but he escapeth not; he is sound asleep, he is insensible. The winds are howling, the thunders are rolling across the sky, and the lightnings flash at his window; but he that can sleep on careth not for these, and is insensible to them all. The sweetest music is passing through the street; but he sleeps, and only in dreams doth he hear the sweetness. The most terrific wailings may assail his ears; but sleep has sealed them with the wax of slumber, and he hears not. Let the world break in sunder, and the elements go to ruin, keep him asleep, and he will not perceive it. Christian, behold your condition. Have you not sometimes been brought into a condition of insensibility? You wished you could feel; but all you felt was pain because you could not feel. You wished you could pray. It was not that you felt prayerless, but it was because you did not feel at all. You sighed once; you would give a world if you could sigh now. You used to groan once; a groan now would be worth a golden star if you could buy it. As for songs, you can sing them, but then your heart does not go with them. You go to the house of God; but when "the multitude that keep holy day" in the full tide of song send their music up to heaven, you hear it, but your heart does not leap at the sound. Prayer goeth solemnly like the evening sacrifice up to God's throne; once you could pray too; but now, while your body is in the house of God, your heart is not there. You feel you have brought the chrysalis of your being; but the fly is gone away from it: it is a dead, lifeless case. You have become like a formalist.
(C. H. Spurgeon.)
