You said;
“It’s a brazen UNBiblical lie that all roads lead to God and Heaven.”
You seem to be indicating the Shack says that. It says the opposite;
Not at all,” smiled Jesus as he reached for the door handle to the shop. “Most roads don’t lead anywhere. What it does mean is that I will travel any road to find you.
If you disagree with the theology of the Shack at least disagree with something it actually says.
It’s been a long time since I read it. I no longer carry quotes from it in my head. It seems to me there was a kind of impression left in some passages that other roads could lead to God. I don’t know, at this point. Others insist that’s in the book. Thankfully what you stated IS in the book.
