Then the sign of the Son of Man will appear in heaven, and all the tribes of the earth will mourn. They will see the Son of Man arriving on the clouds of heaven with power and great glory.
For if anyone is ashamed of me and my words in this adulterous and sinful generation, the Son of Man will also be ashamed of him when he comes in the glory of his Father with the holy angels.”
And he said to them, “I tell you the truth, there are some standing here who will not experience death before they see the kingdom of God come with power.”
and said, “Men of Galilee, why do you stand here looking up into the sky? This same Jesus who has been taken up from you into heaven will come back in the same way you saw him go into heaven.”
For the Lord himself will come down from heaven with a shout of command, with the voice of the archangel, and with the trumpet of God, and the dead in Christ will rise first.
For we did not follow cleverly concocted fables when we made known to you the power and return of our Lord Jesus Christ; no, we were eyewitnesses of his grandeur.
(Look! He is returning with the clouds, and every eye will see him, even those who pierced him, and all the tribes on the earth will mourn because of him. This will certainly come to pass! Amen.)
