AFTER GREAT TRIBULATION
"Immediately after the tribulation of those days the sun will be darkened, the moon will not give its light, and the stars will fall from heaven, and the powers of the heavens will be shaken." (Matt 24:29. See Luke 21:11 & Rev 6:12-14).
"I will show portents in the sky and on earth, blood and fire and columns of smoke; the sun shall be turned into darkness and the moon into blood, before the great and terrible day of the Lord comes. Then, everyone who invokes the Lord by name shall be saved." (From Joel 2:30,31 NEB) (See Acts 2:19-21).
"Portents will appear in sun, moon, and stars. On earth nations will stand helpless, not knowing which way to turn from the roar and surge of the sea; men will faint with terror at the thought (expectation. NWT) of all that is coming upon the world; for the celestial powers will be shaken." (Luke 21:25,26 NEB).
"Fools who long for the day of the Lord, what will the day of the Lord mean to you? It will be darkness, not light. It will be as when a man runs from a lion, (1) and a bear meets him, or turns into a house and leans his hand on the wall, and a snake bites him. The day of the Lord is indeed darkness, not light, a day of gloom with no dawn." (Amos 5:18-20 NEB (1)).
"The day of the Lord is
at hand in the Valley of decision; sun and moon are
darkened and the stars forbear to shine. The Lord roars from Zion
and thunders from Jerusalem; heaven and earth shudder, but the Lord is a refuge
for His people and the defence of Israel."
(From Joel 3:14
(1) To hide from the vengeance of The Lion of God. (See Rev 6:16,17 NEB).
