What people teach as Biblical truth based on interpretations of a few select Scriptures does not indicate the Bible was changed, corrupted, or altered. The smoke of corpses of men who die by fire does not prove that a just and righteous God will torment those who reject His truth throughout eternity.
What I find a bit hypocritical concerning your posts is your appeal to those Scriptures you see as supporting your thesis and ignoring those Scriptures that do not.
Psalms 88:10
10 Wilt Thou perform wonders for the dead?
Will the departed spirits rise and praise Thee?
NAS
Psalms 115:17-18
17 The dead do not praise the LORD,
Nor do any who go down into silence;
18 But as for us, we will bless the LORD
From this time forth and forever.
Praise the LORD! NAS
Isaiah 66:24
24 "Then they shall go forth and look
On the corpses of the men
Who have transgressed against Me.
For their worm shall not die,
And their fire shall not be quenched;
And they shall be an abhorrence to all mankind."
NAS
