Matthew 24:23-31

Then if anyone says to you [during the great tribulation], ‘Look! Here is the Christ,’ or ‘There He is,’ do not believe it. For false Christs and false prophets will appear and they will provide great signs and wonders, so as to deceive, if possible, even the elect (God’s chosen ones). Listen carefully, I have told you in advance. So if they say to you, ‘Look! He is in the wilderness,’ do not go out there, or, ‘Look! He is in the inner rooms [of a house],’ do not believe it. For just as the lightning comes from the east and flashes as far as the west, so will be the coming [in glory] of the Son of Man [everyone will see Him clearly]. Wherever the corpse is, there the vultures will flock together. [Job 39:30] “Immediately after the tribulation of those days THE SUN WILL BE DARKENED, AND THE MOON WILL NOT PROVIDE ITS LIGHT, AND THE STARS WILL FALL from the sky, and the powers of the heavens will be shaken. [Is 13:10; 34:4; Joel 2:10, 11; Zeph 1:15] And at that time the sign of the Son of Man [coming in His glory] will appear in the sky, and then all the tribes of the earth [and especially Israel] will mourn [regretting their rebellion and rejection of the Messiah], and they will see the SON OF MAN COMING ON THE CLOUDS OF HEAVEN with power and great glory [in brilliance and splendor]. [Dan 7:13; Rev 1:7] And He will send His angels with A LOUD TRUMPET and THEY WILL GATHER TOGETHER His elect (God’s chosen ones) from the four winds, from one end of the heavens to the other. [Is 27:13; Zech 9:14]
