The Messiah's prophesies as recorded in Matthew chapter 24 describe in great detail not only the spectacular events that are going to be happening around the world as a whole at the time of His return (see also Prophecy), but also where "ground zero" is going to be for His return. As also made plain in other books of the Bible, including back in The Older Testament (e.g. "And His feet shall stand in that day upon The Mount Of Olives, which is before Jerusalem on the east" Zechariah 14:4 KJV) He will return first to Jerusalem, a "triumphal entry" very different than the one that resulted in His crucifixion (see Two Very Different Triumphal Entries). It will be a time of wrath upon the two greatest misleaders of the world (see Revelation 13), who at that time will be in Jerusalem. Christ's warning to His people there, at that time, get out.
"And Jesus went out, and departed from the Temple [see "My Father's House"]: and His disciples came to Him for to show Him the buildings of the Temple. And Jesus said unto them, See ye not all these things? verily I say unto you, There shall not be left here one stone upon another, that shall not be thrown down."
"And as He sat upon the mount of Olives, the disciples came unto Him privately, saying, Tell us, when shall these things be? And what shall be the sign of Thy coming, and of the end of the world?"
"And Jesus answered and said unto them, Take heed that no man deceive you. For many shall come in My Name, saying, I am Christ; and shall deceive many. And ye shall hear of wars and rumours of wars: see that ye be not troubled: for all these things must come to pass, but the end is not yet. For nation shall rise against nation, and kingdom against kingdom: and there shall be famines, and pestilences, and earthquakes, in divers places. All these are the beginning of sorrows."
"Then shall they deliver you up to be afflicted, and shall kill you: and ye shall be hated of all nations for My Name's sake. And then shall many be offended, and shall betray one another, and shall hate one another. And many false prophets shall rise, and shall deceive many. And because iniquity shall abound, the love of many shall wax cold. But he that shall endure unto the end, the same shall be saved. And this Gospel of The Kingdom shall be preached in all the world for a witness unto all nations; and then shall the end come."
"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: Then let them which be in Judaea [see also Sodom and Egypt] flee into the mountains: Let him which is on the housetop not come down to take any thing out of his house: Neither let him which is in the field return back to take his clothes. And woe unto them that are with child, and to them that give suck in those days! But pray ye that your flight be not in the winter, neither on the sabbath day: For then shall be great tribulation, such as was not since the beginning of the world to this time, no, nor ever shall be [see Never Before, Never Again]. And except those days should be shortened, there should no flesh be saved: but for the elect's sake those days shall be shortened. Then if any man shall say unto you, Lo, here is Christ, or there; believe it not. For there shall arise false Christs, and false prophets, and shall show great signs and wonders; insomuch that, if it were possible, they shall deceive the very elect. Behold, I have told you before."
"Wherefore if they shall say unto you, Behold, he is in the desert; go not forth: behold, he is in the secret chambers; believe it not. For as the lightning cometh out of the east, and shineth even unto the west; so shall also the coming of the Son of man be [see "For as the lightning cometh" and When Will You Be Judged?]. For wheresoever the carcase is, there will the eagles be gathered together."
"Immediately after the tribulation of those days shall the sun be darkened, and the moon shall not give her light, and the stars shall fall from heaven, and the powers of the heavens shall be shaken: And then shall appear the sign of the Son of man in heaven: and then shall all the tribes of the earth mourn, and they shall see the Son of man coming in the clouds of heaven with power and great glory. And He shall send His angels with a great sound of a trumpet, and they shall gather [see Spiritual and Physical Gatherings] together His elect from the four winds, from one end of heaven to the other." (Matthew 24:1-31 KJV)
