1 Thessalonians 5:2
For yourselves know perfectly that the day of the Lord so comes as a thief in the night.
This present state of things is ever close upon the next world, and resolves itself into it. As when a man is given over, he may die any moment, yet lingers; as an instrument of war may any moment explode, and must at some time; as we listen for a clock to strike, and at length it surprises us; as a crumbling arch hangs, we know not how, and is not safe to pass under, so creeps on this feeble, weary world, and one day, before we know where we are, it will end.
(J. H. Newman, D. D.)
