Many things seem contradictory until we understand them better. Light behaves like both a particle and a wave. I wouldn't expect the creator to be any less complex and intriguing than the things He created. How much of the Bible have you read? There are many parts that I don't understand and many that I dislike, but if you read it as a whole, it's a good way to get to know God. The New Testament especially yields a good portrait of his character. Studying nature is another good way to learn about its creator, and it never ceases to amaze me.
