With an ear open to your musical dialectic, one can be young and become old, can work and rest, be content and sad: in short, one can live.

That the zeal for God's honor is also a dangerous passion, that the Christian must bring with him the courage to swim against the tide instead of with it... accept a good deal of loneliness, will perhaps be nowhere so clear and palpable as in the church, where he would so much like things to be different. Yet he cannot and he will not refuse to take this risk and pay this price... he belongs where the reformation of the church is underway or will again be underway.

Faith is not an art. Faith is not an achievement. Faith is not a good work of which some may boast while others can excuse themselves with a shrug of the shoulders for not being capable of it. It is a decisive insight of faith itself that all of us are incapable of faith in ourselves, whether we think of its preparation, beginning, continuation, or completion.

The best theology would need no advocates; it would prove itself.

Sin is not confined to the evil things we do. It is the evil within us, the evil which we are.

A free theologian works in communication with other theologians...He waits for them and asks them to wait for him. Our sadly lacking yet indispensable theological co-operation depends directly or indirectly on whether or not we are wiling to wait for one another, perhaps lamenting, yet smiling with tears in our eyes.

What is offered to man's apprehension in any specific revelation of Christ is the living God himself.
