instinctive aversion from the light which the gospel brings, and the sincerity and openness which it claims; men, in short, who have come to love darkness rather than light, because their deeds are evil. The day of the Lord will certainly be a surprise to them; it will smite them with sudden terror, as the midnight thief, breaking unseen through door or window, terrifies the defenceless householder; it will overwhelm them with despair, because it will come as a great and searching light,--a day on which God will bring every hidden thing to view, and judge the secrets of men's hearts by Christ Jesus. For those who have lived in darkness the surprise will be inevitable; but what surprise can there be for the children of the light? They are partakers of the Divine nature; there is nothing in their souls which they would not have God know; the light that shines from the great white throne will discover nothing in them to which its searching brightness is unwelcome; Christ's coming is so far from disconcerting them that it is really the crowning of their hopes. The Apostle demands of his disciples conduct answering to this ideal. Walk worthy, he says, of your privileges and of your calling. "Let us not sleep, as do the rest, but let us watch and be sober." "Sleep" is certainly a strange word to describe the life of the worldly man. He probably thinks himself very wide awake, and as far as a certain circle of interests is concerned, probably is so. The children of this world, Jesus tells us, are wonderfully wise for their generation. They are more shrewd and more enterprising than the children of light. But what a stupor falls upon them, what a lethargy, what a deep unconscious slumber, when the interests in view are spiritual. The claims of God, the future of the soul, the coming of Christ, our manifestation at His judgment seat, they are not awake to any concern in these. They live on as if these were not realities at all; if they pass through their minds on occasion, as they look at the Bible or listen to a sermon, it is as dreams pass through the mind of one asleep; they go out and shake themselves, and all is over; earth has recovered its solidity, and the airy unrealities have passed away. Philosophers have amused themselves with the difficulty of finding a scientific criterion between the experiences of the sleeping and the waking state, _i.e._, a means of distinguishing between the kind of reality which belongs to each; it is at least one element of sanity to be able to make the distinction. If we may enlarge the ideas of sleep and waking, as they are enlarged by the Apostle in this passage, it is a distinction which many fail to make. When they have the ideas which make up the staple of revelation presented to them, they feel as if they were in dreamland; there is no substance to them in a page of St. Paul; they cannot grasp the realities that underlie his words, any more than they can grasp the forms which swept before their minds in
