Matthew 24:44

Therefore be ye also ready; for in such an hour as ye think not the Son of Man cometh.

Therefore: Since the exact time is unknown and since faithfulness is required, watch, be on your guard, do not even for a day, an hour, a moment, relax your vigilance. Like a thief in the night His day is coming. The housefather, knowing that a thief is coming some time during the night, will far rather watch all night than take chances, with the result that his house is searched through, as if with his permission. Thus the believers of the last days cannot afford to take chances, there is too much at stake. A state of unremitting watchfulness is required of the followers of Christ, in which they are aware every minute of the seriousness of the situation, one fact always standing out in their minds and being brought out in their lives: The Son of Man is coming, a stern and implacable Judge upon the unbelievers that left His warning unheeded, a merciful and kind Judge upon the believers that were always ready for His coming.
