"immediately after the tribulation of those days the sun will be darkened, and the moon will not give its light; the stars will fall from heaven, and the powers of the heavens will be shaken. -And he will send His angels with a great sound of a trumpet, and they will gather together His elect from the four winds, from one end of heaven to the other."
Matthew 24:29 & 31 (NKJV)
1 Cor 15:51-52 (NKJV)
"Behold, I tell you a mystery: We shall not all sleep, but we shall all be changed - in a moment, in the twinkling of an eye, at the last trumpet. For the trumpet will sound, and the dead will be raised incorruptible, and we shall be changed."
1 Cor 15:51-52 (NKJV)
2 Thessalonians (NKJV)
“not to be soon shaken in mind or troubled, either by spirit or by word or by letter, as if from us, as though the day of Christ had come.-Let no one deceive you by any means; for that Day will not come unless the falling away comes first, and the man of sin is revealed, the son of perdition, - who opposes and exalts himself above all that i called God or that is worshiped, so that he sits as God in the temple of God, showing himself that he is God."
