There is a strange fact about the human mind, a fact that differentiates the mind sharply from the body. The body is limited in ways that the mind is not. One sign of this is that the body does not continue indefinitely to grow in strength and develop in skill and grace. By the time most people are thirty years old, their bodies are as good as they will ever be; in fact, many persons' bodies have begun to deteriorate by that time. But there is no limit to the amount of growth and development that the mind can sustain. The mind does not stop growing at any particular age.

The materialist assumption that spiritual substances do not exist is as much an act of faith as the religious belief in the reality of angels.

We acknowledge but one motive - to follow the truth as we know it, whithersoever it may lead us; but in our heart of hearts we are well assured that the truth which has made us free, will in the end make us glad also.

My chief reason for choosing Christianity was because the mysteries were incomprehensible. What's the point of revelation if we could figure it out ourselves? If it were wholly comprehensible, then it would just be another philosophy.

The rules for reading yourself to sleep are easier to follow than are the rules for staying awake while reading. Get into bed in a comfortable position, make sure the light is inadequate enough to cause slight eyestrain, choose a book that is either terribly difficult or terribly boring-in any event, one that you do not really care whether you read or not-and you will be asleep in a few minutes. Those who are experts in relaxing with a book do not have to wait for nightfall. A comfortable chair in the library will do any time

Ultimately there can be no disagreement between history, science, philosophy, and theology. Where there is disagreement, there is either ignorance or error.

Sin is not only manifested in certain acts that are forbidden by divine command. Sin also appears in attitudes and dispositions and feelings. Lust and hate are sins as well as adultery and murder. And, in the traditional Christian view, despair and chronic boredom - unaccompanied by any vicious act - are serious sins. They are expressions of man's separation from God, as the ultimate good, meaning, and end of human existence.
