[Christians] believe that the living, dynamic activity of love has been going on in God forever and has created everything else. And that, by the way, is perhaps the most important difference between Christianity and all other religions: that in Christianity God is not an impersonal thing nor a static thing—not even just one person—but a dynamic pulsating activity, a life, a kind of drama, almost, if you will not think me irreverent, a kind of dance … (The) pattern of this three-personal life is … the great fountain of energy and beauty spurting up at the very center of reality.
