Without risk, faith is an impossibility.

Christianity does not oppose debauchery and uncontrollable passions and the like as much as it opposes... flat mediocrity, this nauseating atmosphere, this homey, civil togetherness, where admittedly great crimes, wild excesses, and powerful aberrations cannot easily occur - but where God's unconditional demand has even greater difficulty in accomplishing what it requires: the majestic obedience of submission.

No grand inquisitor has in readiness such terrible tortures as has anxiety and no spy knows how to attack more artfully the man he suspects, choosing the instant when he is weakest; nor knows how to lay traps where he will be caught and ensnared as anxiety knows how, and no sharp-witted judge knows how to interrogate, to examine the accused, as anxiety does, which never lets him escape.

However much one generation learns from another, it can never learn from its predecessor the genuinely human factor. In this respect every generation begins afresh. Thus no generation has learned from another how to love, no generation can begin other than at the beginning.

Whoever thou art, whatever in other respects thy life may be, my friend, by ceasing to take part (if ordinarily thou doest) in the public worship of God, as it now is (with the claim that it is the Christianity of the New Testament), thou hast constantly one guilt the less, and that a great one: thou dost not take part in treating God as a fool by calling that the Christianity of the New Testament which is not the Christianity of the New Testament.

Every day I walk myself into a state of well-being and walk away from every illness; I have walked myself into my best thoughts.
