If you set aside two thousand years of church history and go back to the Scriptures on which that two-thousand-year-old church bases its authority – that is, the Old and New Testaments – you will see that everyone is going to heaven.
The way to see this is to start with the Old Testament. It is clear that the Old Testament teaching was that everyone who died descended to Sheol (Hades). Everyone. There was a hope of resurrection, but nothing more. Then the New Testament, in the story of Christ, explained how resurrection was going to work. The big surprise – even for believing Jews – was that resurrection led to heaven. They had been assuming that it led back to earth. Jesus shocked them with this revelation.
Once it was clear that resurrection led to heaven, the only thing left to ask was “Who would be raised?” The New Testament answer was clear: the dead.
Since everyone died and the dead would be raised and resurrection led to heaven, then it’s clear that everyone goes to heaven. Of course, there’s much more biblical corroboration of this but I’ve laid out the essential logic.
What people call hell (Jesus called it Gehenna) is the judgment for sin that consumes the earth. It is thus on this earth and in this life. It is not something that happens elsewhere after this life. Hell is a real thing and it is an awful thing, but it is something the Lord gives us the means to escape. And right relationship with Him is the means of escape.
The heaven-or-hell afterlife scenario under which the post-NT church has erroneously labored for almost two thousand years is a theological perversion of Scriptural truth. And the longer that error holds sway, the more frightened people are to challenge it. The way to challenge it is not with intellect or emotion, but with the Scriptures.
To God be the glory!
