It has been proven to be so many times over. In addition, because of John 5:31, one may know that the Anointed one was not speaking of himself when he spoke the words which Zeke referenced and you are responding to, (Luke 17:20,21), but rather, he was speaking of the Word, that is, the very Anointing which was upon him and in his heart. The "abomination of desolation" likewise takes place in the heart; for that spirit rises up and makes a stand in the hearts of men who are in rebellion, (Luke 16:15 expounds this), each in his or her own appointed times, (and none shall be alone in his appointed times).
If you truly believe the Testimony of the Master then look up how many times he uses the word for abomination, (βδελυγμα), in the four Gospel accounts: the answer should astound you and lead you into the correct understanding. Here is a hint: I already quoted one of the passages and the other two occurrences in the Gospel accounts are actually two different accounts of one same statement. Thus he only actually used the word for abomination twice; and therefore the one which I have already noted should define the other for you, (if indeed you love the Word).
