Conscience is the perfect interpreter of life.

God listens to Bach while the angels listen to Mozart.

The relation of this God with this man; the relation of this man with this God--this is the only theme of the Bible and of philosophy.

True theology is an actual determination and claiming of man by the acting God.

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 labors without joy is not a theologian at all. Sulky faces, morose thoughts and boring ways of speaking are intolerable in this field.

Man can certainly keep on lying... but he cannot make truth falsehood. He can certainly rebel... but he can accomplish nothing which abolishes the choice of God.
