But understand this, if the homeowner had known at what hour the thief was coming, he would not have let his house be broken into. Luke 12:39

For you are fully aware, that the day of the Lord will come like a thief in the night. But you, brothers and sisters, are not in the darkness, so that this day should overtake you like a thief. For you are all children of light, children of the day. We are not of the night or of the darkness. So then, let us not sleep, as others do, but let us keep awake and be sober. 1 Thessalonians 5:2,4-6
