I believe in God. In fact, I believe in a personal God who acts in and interacts with the creation. I believe that the observations about the orderliness of the physical universe, and the apparently exceptional fine-tuning of the conditions of the universe for the development of life suggest that an intelligent Creator is responsible.
I believe in God because of a personal faith, a faith that is consistent with what I know about science.
Being an ordinary scientist and an ordinary Christian seems perfectly natural to me. It is also perfectly natural for the many scientists I know who are also people of deep religious faith.
