“Those who are stuck here (unbelievers in Christ) will have two choices:
Convert to the A/C and his system of deity worship while taking his mark or die in faith in Christ.”
Then why does the Bible tell us that there will be living believers who are transformed at the same time the dead believers are resurrected, which happens when Christ returns, at the end of the tribulation?
You are quoting 1 Thessalonians 4:16-17
Read it here:
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. 17Then we who are alive and remain will be caught up together with them in the clouds to meet the Lord in the air, and so we shall always be with the Lord.
Here’s another in 1 Corinthians 15:51-55:
51 Listen, I tell you a mystery: We will not all sleep, but we will all be changed— 52 in a flash, in the twinkling of an eye, at the last trumpet. For the trumpet will sound, the dead will be raised imperishable, and we will be changed. 53 For the perishable must clothe itself with the imperishable, and the mortal with immortality. 54 When the perishable has been clothed with the imperishable, and the mortal with immortality, then the saying that is written will come true: “Death has been swallowed up in victory.”[h]
55 “Where, O death, is your victory?
Where, O death, is your sting?”[i]
Does this sound like the end of the tribulation?
If so, then you got to answer this:
Who repopulates the world after the tribulation if Christ comes to take away all of His people from the Earth and then slays every ungodly person?
Revelation 20:8 specifically mentions a world at the END of the Millennium that has a population vastly larger than anything we have today that is destroyed on the last uprising against Christ and Jerusalem. They have to come from somewhere.
