The answer to every question NOT in the Bible. Every word of the Bible is true but all truth is not there. Why that is in itself a mystery.
I have listened to many arguments about what happens to the souls of the unsaved. My conclusion so far is that it is a mystery.
No person who loves Jesus would wish hell on anyone. Loosing a soul to hell is devastating to Jesus. I prefer to see him rejoice.
2 Timothy 3:16-17, "All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness: That the man of God may be perfect, throughly furnished unto all good works."
We don't need to know exactly what happens when we die aside from what the Bible tells us because if we do as the Bible says, we have no fear of it. We are given no sanction to say "what if," neither in our personal decision nor our urgency for the decision of others.
