...the reason for [this age's] anxiety and unrest is because in one direction, 'truth' increases in scope and quantity - via science and technology - while in the other, certainty and confidence steadily decline. Our age is a master in developing truths while being wholly indifferent to certitude. It lacks confidence in the good.

To despair over one's sins indicates that sin has become or wants to be internally consistent. It wants nothing to do with the good, does not want to be so weak as to listen occasionally to other talk. No, it insists on listening only to itself, on having dealings only with itself; it closes itself up within itself, indeed, locks itself inside one more inclosure, and protects itself against every attack or pursuit by the good by despairing over sin.

The truth must essentially be regarded as in conflict with this world; the world has never been so good, and will never become so good that the majority will desire the truth.

Most men pursue pleasure with such breathless haste that they hurry past it.

...the greatest thing each person can do is to give himself to God utterly and unconditionally - weaknesses, fears, and all. For God loves obedience more than good intentions or second-best offerings, which are all too often made under the guise of weakness.

It is the duty of the human understanding to understand that there are things which it cannot understand.

In a mathematical proposition, for example, the objectivity is given, but therefore its truth is also an indifferent truth.
