Let us begin with the inaccuracy of the highlighted statement.
I never espoused that idea. I believe in a total end to evil. It will be done away with, destroyed utterly. As The King said in Matthew 10:28.
Now let's get to the meat and cease with the milk in this thread.
1. Is God good?
2. Can God do evil things?
3. If God does things that evil doers do can he be God?
Have at it. Let's really get down to the heart of the matter.
[Ecc 12:7 KJV] Then shall the dust return to the earth as it was: and the spirit shall return unto God who gave it.
The soul isn't mentioned because:
[1Co 15:44-49 KJV] 44 It is sown a natural body; it is raised a spiritual body. There is a natural body, and there is a spiritual body. 45 And so it is written, The first man Adam was made a living soul; the last Adam [was made] a quickening spirit. 46 Howbeit that [was] not first which is spiritual, but that which is natural; and afterward that which is spiritual. 47 The first man [is] of the earth, earthy: the second man [is] the Lord from heaven. 48 As [is] the earthy, such [are] they also that are earthy: and as [is] the heavenly, such [are] they also that are heavenly. 49 And as we have borne the image of the earthy, we shall also bear the image of the heavenly.
So let's look at these examples of "for ever and ever" and how you seem to pick and choose that not all men will be in the Lake of Fire for ever and ever...
[Exo 15:18 KJV] 18 The LORD shall reign for ever and ever.
[Psa 9:5 KJV] 5 Thou hast rebuked the heathen, thou hast destroyed the wicked, thou hast put out their name for ever and ever.
[Psa 10:16 KJV] 16 The LORD [is] King for ever and ever: the heathen are perished out of his land.
[Psa 45:6 KJV] 6 Thy throne, O God, [is] for ever and ever: the sceptre of thy kingdom [is] a right sceptre.
[Phl 4:20 KJV] 20 Now unto God and our Father [be] glory for ever and ever. Amen.
[1Ti 1:17 KJV] 17 Now unto the King eternal, immortal, invisible, the only wise God, [be] honour and glory for ever and ever. Amen.
[Rev 11:15 KJV] 15 And the seventh angel sounded; and there were great voices in heaven, saying, The kingdoms of this world are become [the kingdoms] of our Lord, and of his Christ; and he shall reign for ever and ever.
[Rev 14:11 KJV] 11 And the smoke of their torment ascendeth up for ever and ever: and they have no rest day nor night, who worship the beast and his image, and whosoever receiveth the mark of his name.
[Rev 20:10 KJV] 10 And the devil that deceived them was cast into the lake of fire and brimstone, where the beast and the false prophet [are], and shall be tormented day and night for ever and ever.
[Rev 22:5 KJV] 5 And there shall be no night there; and they need no candle, neither light of the sun; for the Lord God giveth them light: and they shall reign for ever and ever.
If you study the times in which God visits His, you'll find a GREAT and TERRIBLE darkness. Wait! God is Light, how is that possible? It's because God is so pure, the all of our impurities (even as Christians in our flesh) are reflected back to us like a mirror:
[1Co 13:12 KJV] 12 For now we see through a glass, darkly; but then face to face: now I know in part; but then shall I know even as also I am known.
So for those who refuse God's gift, they will be surrounded by God's purity without His anoinment so what He rejects (those that rejected Him) having that imperfection, those impurities, sin, all evil reflected back to themselves. That is the torment, that is the burning that lasts
for ever and ever. Sicn our prayers are like incence to God ascending to Heaven (Psalm 141:2), their smoke of torment is their cries of anguish ascend for ever and ever (Rev 14:11).
