WHO IS GOD?

"GOD is the name commonly given to the ultimate source and power of the universe and the subject of religious devotion," says The Encyclopedia Americana. A dictionary defines the term "God" as "the supreme or ultimate reality." What is the nature of such an awesome reality?
Is God an impersonal force or a real person? Does he have a name? Is he a triune entity, a Trinity, as many believe?
An Impersonal Force or a Real Person?
Many who believe in God think of him as a force, not as a person. In certain cultures, for example, gods have been identified with the forces of nature. Some who have examined evidence gathered through scientific research into the structure of the universe and the nature of life on earth have concluded that there has to be a First Cause. Nevertheless, they hesitate to attach a personality to this Cause.
