That is because when Christ comes again to earth, the people of God remain on the earth and the wicked are swept away in a destruction that leaves them neither root nor branch, they are gone, burned up in fiery wrath, while the people of God inherit the earth (new earth)
The NT apostles and OT prophets agree completely
Malachi 4
1 “For behold, the day is coming,
Burning like an oven,
And all the proud, yes, all who do wickedly will be stubble.
And the day which is coming shall burn them up,”
Says the Lord of hosts,
“That will leave them neither root nor branch.
2 But to you who fear My name
The Sun of Righteousness shall arise
With healing in His wings;
And you shall go out
And grow fat like stall-fed calves.
3 You shall trample the wicked,
For they shall be ashes under the soles of your feet
On the day that I do
this,”
Says the Lord of hosts.
2 Thess 1
6 since
it is a righteous thing with God to repay with [
c]tribulation those who trouble you,
7 and to
give you who are troubled rest with us when the Lord Jesus is revealed from heaven with His mighty angels,
8 in flaming fire taking vengeance on those who do not know God, and on those who do not obey the gospel of our Lord Jesus Christ.
9 These shall be punished with everlasting destruction from the presence of the Lord and from the glory of His power,
10 when He comes, in that Day, to be glorified in His saints and to be admired among all those who [
d]believe, because our testimony among you was believed.
2 Thess 1 AND Malachi 4 also implies their location!
Which is the righteous saints were on the earth on the Last Day living among the wicked and the Great Day of God came and they inherit the earth.
