Why is the "Modern Western God" the Correct One?

Although I’ve had this question asked of me several times, one person seemed to really dig deep into the issue. She went on to ask:

“We seem to discount ‘Gods’ one by one as time goes by. We see the ancient Greek/Roman gods as complete mythology now. What makes people so sure that this is the real thing not just the evolution of old and now discounted or discarded religion?”

I believe this question has three main parts so I will try to address them all. The first part asks why the “modern Western God was the correct one?” This question can be confusing so for my answer I’ll assume that the “Western God” referred to is the same God that the Christian majority in the United States worships. We need to understand that this God does not have his roots in the western world. In fact, it is the very same God that was first worshiped on the exact opposite side of the world; what we now refer to as the Middle East. Knowledge of God spread from the Middle East, to Europe first, then to Asia and Africa, and then finally over 1500 years later, to the United States. You see the Western God is not a Western God at all, but the same God worshiped by people in every country and every continent all over the world.

The second part of the question deals with the “discounting of Ancient Greek/Roman gods.” It is important to note that the Jews had a knowledge of the one true God long before the Greek/Roman gods came into existence. It is also important to note that it was not the appearance of Jesus, (in other words the beginning of the Christian religion), which caused people to automatically discount Greek/Roman gods. During the 6th century BC the advent of materialistic Greek Philosophy first came onto the scene (guys like Plato, Aristotle, and Socrates). It was this advent of philosophy that effectively destroyed the faith of the Greek people in their multitude of gods and not the appearance of Jesus as he wouldn’t come for another 600 years.

Thirdly, the reason we can be assured that this is the real thing and not just some “god evolution” is because the Bible shows us that God has been actively engaging with people since the very beginning of time. Evolution by its very definition requires a changing over a period of time. We can see through the Bible that the person of God is unchanging. He is the same as he’s always been and He will always be the same. We can also see that because people have been interacting with him since the beginning, this is not some new religion that people just invented a few decades ago. The principles in the Bible can also be tested and found to be relevant in all cultures through all times. Something else worth noting is that the passing of time, usually wipes away wrong beliefs. Remember when people thought the earth was flat or that the earth was the center of the universe? We can look back through the pages of history and see that not only has Christianity stood the test of time, but that God hasn't changed.
