Weird question, I know. The idea was first introduced to me years ago when I read CS Lewis' Chronicles of Narnia series. I actually took a course in college exclusively studying Lewis, I digress. I know you enjoy Tolkien's work too, as do I, I digress again.
Long story short, in the final installment of Narnia (The Last Battle), Narnia goes through their end times (similar to the book of Revelation). During Judgement Day, Aslan (Jesus), comes across a man named Emeth. Emeth fought for the opposing false god, Tash, and followed the false god's teaching (or thought he was), seemingly his whole life. However, when he is judged, Aslan judges his heart and concludes that his actions spoke virtuously and Aslan accepted Emeth's devotion to Himself. I suppose, the false god, Tash, would never inspire someone to act virtuously, so really he was never worshiping Tash, but actually Aslan.
This view from Lewis has been in my thoughts for years. I believe that we are all created with our Creator's imprint. No matter where we are born in the world, what religion or culture we're born into, we still have the True Hand print on our soul. I believe that is why we all have a basic understanding of right and wrong in our heart of hearts. So, with the billions of people in the world, who, in my opinion, are given very less than favorable odds to find Christ and live for Him, is it feasible to think God will accept many of those into eternity? We know God judges our heart. Not our words or perhaps even who we think we're worshiping, but simply our heart.
