An interesting way to look at this is when Christ returns, all the dead in Christ are raised and all the believers are gathered to Him by His angels (raptured) to be with Him off the earth in the air.
So, then WHO is left on the earth?
At the time of His appearing, we have the great tribulation, the beast followers, one world government of Satan.
All those people did not want Christ to reign over them, so they will all be slain when He judges the world in righteousness.
The Parable of the Minas
11 Now as they heard these things, He spoke another parable, because He was near Jerusalem and because they thought the kingdom of God would appear immediately.
12
Therefore He said: “A certain nobleman went into a far country to receive for himself a kingdom and to return.
13 So he called ten of his servants, delivered to them ten [e]minas, and said to them, ‘Do business till I come.’
14 But his citizens hated him, and sent a delegation after him, saying, ‘We will not have this man to reign over us.’
15 “And so it was that when he returned, having received the kingdom, he then commanded these servants, to whom he had given the money, to be called to him, that he might know how much every man had gained by trading. 16 Then came the first, saying, ‘Master, your mina has earned ten minas.’ 17 And he said to him, ‘Well
done, good servant; because you were faithful in a very little, have authority over ten cities.’ 18 And the second came, saying, ‘Master, your mina has earned five minas.’ 19 Likewise he said to him, ‘You also be over five cities.’
20 “Then another came, saying, ‘Master, here is your mina, which I have kept put away in a handkerchief. 21 For I feared you, because you are [
f]an austere man. You collect what you did not deposit, and reap what you did not sow.’ 22 And he said to him, ‘Out of your own mouth I will judge you,
you wicked servant. You knew that I was an austere man, collecting what I did not deposit and reaping what I did not sow. 23 Why then did you not put my money in the bank, that at my coming I might have collected it with interest?’
24 “And he said to those who stood by, ‘Take the mina from him, and give
it to him who has ten minas.’ 25 (But they said to him, ‘Master, he has ten minas.’) 26 ‘For I say to you, that to everyone who has will be given; and from him who does not have, even what he has will be taken away from him.
27
But bring here those enemies of mine, who did not want me to reign over them, and slay them before me.’ ”
