You've almost got it! What happens when "the Son of Man" (Jesus) returns?
Here's a hint,
Matthew 24:30-31 New International Version (NIV)
“Then will appear the sign of the Son of Man in heaven.
And
then all the peoples of the earth will mourn when they see the Son of Man coming on the clouds of heaven, with power and great glory. And he will send his angels with a loud trumpet call, and they will gather
his elect from the four winds, from one end of the heavens to the other.
To his elect this will happen:
1 Thessalonians 4:16-17 New International Version (NIV)
For the Lord himself will come down from heaven, with a loud command, with the voice of the archangel and with the trumpet call of God, and the dead in Christ will rise first.
After that, we who are still alive and are left will be caught up together with them in the clouds to meet the Lord in the air. And so we will be with the Lord forever.
To those who are left behind this will happen:
2 Peter 3:10-12New International Version (NIV)
But the day of the Lord will come like a thief. The heavens will disappear with a roar; the elements will be destroyed by fire, and the earth and everything done in it will be laid bare.
Since everything will be destroyed in this way, what kind of people ought you to be? You ought to live holy and godly lives as you look forward to the day of God and speed its coming. That day will bring about the destruction of the heavens by fire, and the elements will melt in the heat.
