When you can come up with one single verse in the Bible that clearly shows one individual (angel, human, or otherwise), being allowed out of the Lake of Fire, or leaving the Lake of Fire, then your argument might become more legitimate. It doesn't matter how many people you can say agree with what you say, your basic premise is destroyed by the light of the Word of God. It doesn't matter how many convincing arguments you try to write up, you cannot ever and will not ever be able to quantify the belief that someone in the Lake of Fire comes out.
Tell you what PK. I'll make you a deal.
Rev. 6: 12 I watched as he opened the sixth seal. There was a great earthquake. The sun turned black like sackcloth made of goat hair, the whole moon turned blood red, 13 and the stars in the sky fell to earth, as late figs drop from a fig tree when shaken by a strong wind. 14 The sky receded like a scroll, rolling up, and every mountain and island was removed from its place.
Explain to me how in ch. 6 the sun turns black, the moon red, the stars fell to the earth, the sky has receeded and every mountain and island has been removed.
“Then”, that’s the way the next verse starts. Verse 15, THEN the kings of the earth, the princes, the generals, the rich, the mighty, and every slave and every free man hid in caves and among the rocks of the mountains. 16 They called to the mountains and the rocks, "Fall on us and hide us from the face of him who sits on the throne and from the wrath of the Lamb!
My goodness. The sun is black. The stars have fallen to the earth. The sky has receeded. Every mountain and island removed. And…. People are still running around alive???
Not only that, but they are hiding among the mountains which have been removed. They want the mountains which have been removed to fall on them.
You explain that to me and I will explain why there is no mention of anyone being let out of the Lake of Fire.
You get my point? My point is, I would think twice before I made the symbolic Lake of Fire a dividing line of whether or not God was going to torment millions for eternity as a sign of His justice.
Is that going to be your defense to God when He asks you why you continued to preach such a doctrine? To which God would likely reply, “My goodness PK. Didn’t you know symbolism when you saw it?”
