Matthew 24:4-26 KJV
[4] And Jesus answered and said unto them, Take heed that no man deceive you. [5] For many shall come in my name, saying, I am Christ; and shall deceive many. [6] 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. [7] For nation shall rise against nation, and kingdom against kingdom: and there shall be famines, and pestilences, and earthquakes, in divers places. [8] All these are the beginning of sorrows. [9] 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. [10] And then shall many be offended, and shall betray one another, and shall hate one another. [11] And many false prophets shall rise, and shall deceive many. [12] And because iniquity shall abound, the love of many shall wax cold. [13] But he that shall endure unto the end, the same shall be saved. [14] 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. [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:) [16] Then let them which be in Judaea flee into the mountains: [17] Let him which is on the housetop not come down to take any thing out of his house: [18] Neither let him which is in the field return back to take his clothes. [19] And woe unto them that are with child, and to them that give suck in those days! [20] But pray ye that your flight be not in the winter, neither on the sabbath day: [21] For then shall be great tribulation, such as was not since the beginning of the world to this time, no, nor ever shall be. [22] And except those days should be shortened, there should no flesh be saved: but for the elect's sake those days shall be shortened. [23] Then if any man shall say unto you, Lo, here is Christ, or there; believe it not. [24] For there shall arise false Christs, and false prophets, and shall shew great signs and wonders; insomuch that, if it were possible, they shall deceive the very elect. [25] Behold, I have told you before. [26] 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.
these are the very things His disciples witnessed, yeah great tribulation!!!!!!
