Matthew 24

 (Matthew 24:3-8, 21-22, 29-31, 36, 42& 44) 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."

"For then shall be great tribulation, such as was not since the beginning of the world to this time, no, nor ever shall be. And except those days should be shortened, there should no flesh be saved: but for the elect's sake those days shall be shortened."

"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 together his elect from the four winds, from one end of heaven to the other."

"But of that day and hour knoweth no man, no, not the angels of heaven, but my Father only. Watch therefore: for ye know not what hour your Lord doth come. Therefore be ye also ready: for in such an hour as ye think not the Son of man cometh."
