Astronomer Dr. Hugh Ross recounts that it was his study of astronomy that led him to believe that there has to be a God. Once he knew that, he began a journey of looking into all the holy books that undergird the religions of the world.
What Dr. Ross had found to be unique to the Bible was that it was clear and it was direct. It mentions geography, history and science. It was the only text that he had picked up that had actually exhorted him to put everything it had said to an objective test.
So for about 18 months, Dr. Ross ploughed through the bible every day. He was not able to find any single provable error or contradiction. Moreover, unlike the other holy books, the Bible predicted future historical events and future scientific discoveries accurately.
Therefore, Dr. Ross realized that the only this was possible is that the authors of the bible were inspired by the One who actually created all matter, energy, space and time.
You alone are the Lord;
You have made heaven,
The heaven of heavens, with all their host,
The earth and everything on it,
The seas and all that is in them,
And You preserve them all.
The host of heaven worships You.
