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 Spirit bears witness. Ecstasy and enlightenment, inspiration and intuition are not necessary. Happy is the man who is worthy of these; but woe unto us if we wait for such experiences; woe unto us if we do not perceive that these things are of secondary importance.

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.

The theologian who labours without joy is not a theologian at all.

It is always the case that when the Christian looks back, he is looking at the forgiveness of sins.

I have read many books, but the Bible reads me.

The Truth lies not in the Yes and not in the No, but in the knowledge and the beginning from which the Yes and the No arise.
