Signs of Christ's return

Now when He had spoken these things, while they watched, He was taken up, and a cloud received Him out of their sight. And while they looked steadfastly toward heaven as He went up, behold, two men stood by them in white apparel, who also said, "Men of Galilee, why do you stand gazing up into heaven? This same Jesus, who was taken up from you into heaven, will so come in like manner as you saw Him go into heaven."

—Acts 1:9-11

1. The coming of Christ will be instantaneous and worldwide. "For as the lightning comes from the east and flashes to the west, so also will the coming of the Son of Man be." —Matthew 24:27
2. The coming of Christ will be visible to all. "Then the sign of the Son of Man will appear in heaven, and then all the tribes of the earth will mourn, and they will see the Son of Man coming on the clouds of heaven with power and great glory." —Matthew 24:30
3. The coming of Christ will be audible. "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 24:31
4. The resurrection of the righteous will occur. "For the Lord Himself will descend from heaven with a shout, with the voice of the archangel, and with the trumpet of God. And the dead in Christ will rise first." —1 Thessalonians 4:16
5. In one single event, the saved who are alive at Christ's coming will be caught up together with the resurrected to meet the Lord in the air. "Then we who are alive and remain shall be caught up together with them in the clouds to meet the Lord in the air. And thus we shall always be with the Lord." —1 Thessalonians 4:17
