Well how about this?I agree, the tares are pulled out of the kingdom at the harvest, end of the age and I also agree there are only two conditions of mankind, either saved or unsaved.
John 3:5 Jesus answered, Verily, verily, I say unto thee, Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God.
What is your explanation for how the tares get into the kingdom in the first place when only the saved can enter the kingdom?
Revelation 11:15
Then the seventh angel sounded: And there were loud voices in heaven, saying, “The kingdoms of this world have become the kingdoms of our Lord and of His Christ, and He shall reign forever and ever!”
Christ takes up His great power and reigns. He takes over, in a sense, an invasion if you like. To the winner goes the spoils.
The field is the world, and the earth is the Lord's, ultimately He does what He wants with His own things.
Satan is a liar, and either lies about the world being given to him, or he stole it.
Psalm 24
1 The earth is the Lord’s, and all its fullness,
The world and those who dwell therein.
2 For He has founded it upon the seas,
And established it upon the [a]waters.
