'Thief' in the Bible
But understand this: If the head of the house had known what time of the night the thief was coming, he would have been on the alert and would not have allowed his house to be broken into.
“Sell your possessions (show compassion) and give [donations] to the poor. Provide money belts for yourselves that do not wear out, an unfailing and inexhaustible treasure in the heavens, where no thief comes near and no moth destroys.
“I assure you and most solemnly say to you, he who does not enter by the door into the sheepfold, but climbs up from some other place [on the stone wall], that one is a thief and a robber.
The thief comes only in order to steal and kill and destroy. I came that they may have and enjoy life, and have it in abundance [to the full, till it overflows].
Now he said this, not because he cared about the poor [for he had never cared about them], but because he was a thief; and since he had the money box [serving as treasurer for the twelve disciples], he used to pilfer what was put into it.
The thief [who has become a believer] must no longer steal, but instead he must work hard [making an honest living], producing that which is good with his own hands, so that he will have something to share with those in need.
For you yourselves know perfectly well that the day of the [return of the] Lord is coming just as a thief [comes unexpectedly and suddenly] in the night.
But you, believers, [all you who believe in Christ as Savior and acknowledge Him as God’s Son] are not in spiritual darkness [nor held by its power], that the day [of judgment] would overtake you [by surprise] like a thief;
Make sure that none of you suffers as a murderer, or a thief, or any sort of criminal [in response to persecution], or as a troublesome meddler interfering in the affairs of others;
But the day of the Lord will come like a thief, and then the heavens will vanish with a [mighty and thunderous] roar, and the [material] elements will be destroyed with intense heat, and the earth and the works that are on it will be burned up.
So remember and take to heart the lessons you have received and heard. Keep and obey them, and repent [change your sinful way of thinking, and demonstrate your repentance with new behavior that proves a conscious decision to turn away from sin]. So then, if you do not wake up, I will come like a thief, and you will not know at what hour I will come to you.
(“Behold, I am coming like a thief. Blessed is he who stays awake and who keeps his clothes [that is, stays spiritually ready for the Lord’s return], so that he will not be naked—spiritually unprepared—and men will not see his shame.”)
