“But of that day and hour knoweth no man, but my Father only” (Matthew 24:36), is what Christ says, for it may come any time, at any moment, even when we do not expect it.
In reply to the question when this hour shall arrive, Christ says that we cannot know it; but for the very reason that we do not know the time of its coming, we should not only be at all times prepared to meet it, as must be the goodman watching the house, and the virgins with their lamps going forth to meet the bridegroom, but also we should work with all our strength for the coming of that hour, as the servants had to work for the talents given to them (Matthew 24:43; 25:1–30). In reply to the question when this hour should come, Christ admonished all men to work with all their strength for its quicker coming.
There can be no other answer. People can nowise know when the day and the hour of the kingdom of God shall arrive, because the coming of that hour depends on no one but the men themselves.
The answer is the same as that of the sage, who in reply to the question of a passerby, how far it was to the city, answered, “Go.”
How can we know how far it is to the goal toward which humanity is moving, since we do not know how humanity, on whom it depends whether to go or not, to stop, to temper the motion, or to accelerate it, will move toward that goal?
All we can know is, what we, who compose humanity, must do, and what not, in order that the kingdom of God may come. That we all know. And everyone need but begin to do what we must do, and stop doing what we must not do; every one of us need only live by all that light which is within us, in order that the promised kingdom of God, toward which the heart of every man is drawn, may come at once.
