I felt what you were saying is that Elijah is not in heaven because he did not go to heaven by way of "Jesus." If Jesus is the only way, yet Elijah went to heaven without Jesus being born, then Elijah cannot be in heaven. That's what I understood about what you were trying to say.
If that is in fact what you were trying to say, then I would have to disagree with your statement. Which is why I responded the way I did.
