“To speak of mystery in a Christian sense means that the human mind is finite and not fully able to understand, deduce or even contain the deep structures of God's reality.”

“The type of mind that can understand good fiction is not necessarily the educated mind, but it is at all times the kind of mind that is willing to have its sense of mystery deepened by contact with reality, and its sense of reality deepened by contact with mystery.”

“In the Christian context, we do not mean by a "mystery" merely that which is baffling and mysterious, an enigma or insoluble problem. A mystery is, on the contrary, something that is revealed for our understanding, but which we never understand exhaustively because it leads into the depth or the darkness of God. The eyes are closed—but they are also opened.”

“I find it easier to believe in God than to believe Hamlet was deduced from the molecular structure of a mutton chop.”

“The mind of God is a mystery and none can understand it.”

“Every aspect of Nature reveals a deep mystery and touches our sense of wonder and awe. Those afraid of the universe as it really is, those who pretend to nonexistent knowledge and envision a Cosmos centered on human beings will prefer the fleeting comforts of superstition. They avoid rather than confront the world. But those with the courage to explore the weave and structure of the Cosmos, even where it differs profoundly from their wishes and prejudices, will penetrate its deepest mysteries.”
