Hi there,
Your OP is just another example to me of why believers and non-believers alike would benefit from reading the Bible for ourselves, without any accompanying Commentary to tell us what it says or means. Because more often than not Scriptures are being overlooked and omitted in order to develop this "firm idea about what happens to the unbeliever". The more I've read the Bible for myself the LESS firm I have become in this particular instance. Let me give you just one example which I'd like to direct in response to the following quote:
Romans 11:32 turns this statement on it's head:
Rom 11:32 For God hath concluded them all in
unbelief, that he might have mercy upon all.
If you read the verses preceding this it just drives the point home. The Apostle Paul even said of himself that he received mercy because he did what he did
ignorantly in unbelief (1 Timothy 1:13). He even goes on to say that his obtaining of mercy was specifically set forward for us as a
pattern of the long suffering of the Lord. (1 Timothy 1:16) Which the Apostle Peter later tells us is salvation (2 Peter 3:15). The last thing worthy of note about the Apostle Paul's conversion
as a pattern is that it only came once the Lord appeared to him directly.
There is so much wrong with that above quote it makes my stomach turn. Especially the part where it says "you may look throughout the entire Bible, and you will not find...". Almost seems like an encouragement to not bother reading the Bible for yourself and instead believing what he says. I only hope it's not intentional by the writer.
