Matthew 24:15 "When ye therefore shall see the abomination of desolation, spoken of by Daniel the prophet, stand in the holy place (whoso readeth, let him understand"
The "abomination" is when Satan stands in Jerusalem, and proclaims that he is God, and the world believes it. The "desolation" is an incorrect translation into the English, which should read "desolator", and Satan is the desolator that will make the claim that he is God, the true Christ. "Desolation" is a condition, in the Hebrew manuscripts it is written, "On the wings of the desolator," this is not a condition, but a entity, a person. It is through this individual, Satan that the abomination shall come from. It is the desolator [Satan] that shall cause all but the sealed of God, to become desolate, or deceived.
Daniel 9:27; "And he shall confirm the covenant with many for one week: and in the midst of the week he shall cause the sacrifice and the oblation to cease, and for the overspreading of abominations he shall make it desolate, even until the consummation, and the determined shall be poured upon the desolate."
The Holy place is the place that the temple sits, and this is the subject for the very first, when the buildings of the temple were observed by the disciples, and the question of what it would be like at His second advent. This is where the desolation [Satan, the Antichrist] shall sit on mount Zion, making his abominations, or statements that he is the Christ.
The world will be deceived when Satan claims himself to be Christ, for he does have supernatural powers, and he will use them to to draw the peoples of the world to come to peace. He will say, I am Jesus whom ye have been waiting for, and I have come to bring peace to the world, and the world will be brought to peace and prosperity by Satan, the Antichrist.
That's why Christ would said,when you say peace and safety,then sudden destruction......
