that is where God’s Kingdom is—in heaven.
The kingdom of God
What? - God's government
Where? - in heaven
(Matthew 13:41-43) . . .The Son of man will send forth his angels, and they will collect out from his kingdom all things that cause stumbling and persons who are doing lawlessness, 42 and they will pitch them into the fiery furnace. There is where [their] weeping and the gnashing of [their] teeth will be. 43 At that time the righteous ones will shine as brightly as the sun in the kingdom of their Father. Let him that has ears listen.
The wicked gathered from - God's kingdom
The anointed will be in - God's kingdom
If the Watchtower's view of the kingdom is correct:
The wicked gathered from - God's government in heaven
The anointed will be in - God's government in heaven
However, the most logical and biblically consistent position would be:
The wicked gathered from - the earth
The anointed will be on - the earth
