I NEVER said that (the statement highlighted in red), nor even alluded to such a thing in any manner whatsoever!
In fact, I do NOT believe any soul, including the body it inhabits, will be cast (alive & fully awake) into the lake of fire UNTIL the end of the coming 1,000 reign of Jesus Christ upon the earth, after which the 2nd resurrection and final judgment transpires.
If such a thing were true, then it surely would represent an act of unrighteousness by God, for neither Satan nor any member of his demonic band have been cast there yet, and they were the first in rebellion against God!
Satan and every member of his demonic band, together with all of the wicked among mankind (both body and soul), will be cast into the lake of fire at the same time. That will be God's righteous justice for willful, sinful rebellion against Him.
Did not even the demons that our Lord encountered in the tombs they cried out,
"saying, What have we to do with thee, Jesus, thou Son of God? art thou come hither to torment us before the time?" (
Matthew 8:29, KJV)
Both Peter and Jude gave witness to the veracity of this fact (see
II Peter 2:4 &
Jude 6, KJV).
Just as God's "righteousness" prohibits Him from casting Satan or the demons into the lake of fire "before the time" appointed, His fairness and equality of justice (righteousness) likewise prohibits Him from casting a wicked man there before the last day as well.
Have you never read (in
Hebrews 6:1-2, KJV) wherein the writer enumerates the six elements which comprises "the principles of the doctrine of Christ" and includes
ETERNAL JUDGMENT?
The word "judgment," as it is here used, could also be properly interpreted to imply/infer "suffering" which awaits all of the wicked dead who will be included as participants in the second resurrection at the end of the coming millennium, and their "suffering" is explicitly stated as
ETERNAL, that is, everlasting, non-ending!
This, again, indicates that the invisible SOUL of mankind is immortal!
