In Matthew's Gospel, Jesus responds to His disciples with the quote mentioned above in Matthew 25:15. Matthew is specifically written for or to the Jews telling them Jesus is indeed their Messiah, their King, their Prince.... Look at what Jesus is saying, "when you see the AOD (Jesus being crucifified) ... let him understand.... and He purposefully points back to Daniel. Specifically, in Daniel 25 - one of the two "restorative" verses. He is their Messiah. And, like any king, one would definitely expect to see a king standing within the holy place - that is where a king should be standing. And Jesus did stand there.
However, in Mark, he offers a very different statement made by Jesus - exact same time and audience. But Mark's Gospel is not speaking to the Jews but to the Gentiles. The Gospel of Mark speaks about Jesus, not as a king or prince, but as a "suffering sevant." And Mark also mentions the phrase that would be said by Jesus..."when you see the AOD standing in a place where he does not belong....." Why would Jesus say this? Because He came as our perfect sacrifice. He is / was indeed our suffering servant and NO servant belongs in the holy place - that is not where servants belong. Jesus is providing different ways to see HIm.. as a conquering king and a suffering servant. And in Mark's Gospel, Jesus is not referring to the same verse as in Matthew. Instead, He is referring to verse 26 - the "destructive" verse where He would be cuts off.
So Jesus is indeed telling His disciples, and us, just who is the AOD is.... can you possibly find an action or event in man's history that could compare to His rejection and crucifixion? The first Temple, the Sanctuary, the streets, the walls, everything was completely destoryed by the Babylonians ... nothing is of greater value could rise to the level of an "abomination" that the cross. And this is why He would make "desolate" His relationship with His people for over 2000 years - the time of the Gentiles. Then, He will restore their sight and they will recognize the One they have pierced.
And if you do not mind, there is another very important verse in Matthew that has been so misunderstood... In Matthew, there is a verse that says, "that unless those days were shortened, no flesh would be saved." EVERYONE contends this is an end time event ususally tied to some mythical anti-Christ figure during a unScriptural 7 year tribulation (there is absolutely no 7 year tribulation). But his particular phrase speaks to the Messiah. The Messiah was crucified exactly 3.5 years (in the midst of the week) of the 7 years of the prophecy. It was Jesus who WILLINGLY went to the cross to say us from our sins. Without the cross, whether Jew of Gentile, NO ONE will pass into heaven with the Lord UNLESS they accept His sacrifice on the cross. Meaning, it was Jesus who willingly shortened those days, and went to the cross, othwerwise no flesh would or could ever be saved.
