Or else; unknown to the master the thief breaks into the house, because while the spirit sleeps instead of guarding itself, death comes unexpectedly, and breaks into the dwelling place of our flesh. But he would resist the thief if he were watching, because being on his guard against the coming of the Judge, who secretly seizes his soul, he would by repentance go to meet Him, lest he should perish impenitent. But the last hour our Lord wishes to be unknown to us, in order as we cannot foresee it, we may be unceasingly preparing for it.
