Context: Jesus, when questioned by his disciples on the Mount of Olives concerning the time and the sign of His Second Coming and of the Day of Judgment, prophesies that many will be led astray by those proclaiming themselves to be Christ, warns them against such false ones, and foretells a time of war and sorrow. Warning of the tribulation of the faithful and the apostasy of the weak, He announces that the message of God will be preached to all lands before the end. When the gospel has been spread and when a holy place has been defiled, the nations of the world will begin their wars. During these times of agony and destruction, Jesus says, there will be false Christs and prophets who would lead astray the very elect. Jesus then gives His disciples a clear description of His own coming at the proper time:
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.. . .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.
