All men's miseries derive from not being able to sit in a quiet room alone.
If we let ourselves believe that man began with divine grace, that he forfeited this by sin, and that he can be redeemed only by divine grace through the crucified Christ, then we shall find peace of mind never granted to philosophers. He who cannot believe is cursed, for he reveals by his unbelief that God has not chosen to give him grace.
Can anything be stupider than that a man has the right to kill me because he lives on the other side of a river and his ruler has a quarrel with mine, though I have not quarrelled with him?
