Doubt is the necessary tool of knowledge.

The abundance of a grateful heart gives honor to God even if it does not turn to Him in words. An unbeliever who is filled with thanks for his very being has ceased to be an unbeliever.

Why does philosophy use concepts and why does faith use symbols if both try to express the same ultimate? The answer, of course, is that the relation to the ultimate is not the same in each case. The philosophical relation is in principle a detached description of the basic structure in which the ultimate manifests itself. The relation of faith is in principle an involved expression of concern about the meaning of the ultimate for the faithful.

There is no place to which we could flee from God, which is outside of God.

Faith as the state of being ultimately concerned implies love, namely, the desire and urge toward the reunion of the seperated.
