On Anxiety

But when once the light of Divine Providence has illumined the believer's soul, he is relieved and set free, not only from the extreme fear and anxiety which formerly oppressed him, but from all care. For as he justly shudders at the idea of chance, so he can confidently commit himself to God. This, I say, is his comfort, that his heavenly Father so embraces all things under his power—so governs them at will by his nod—so regulates them by his wisdom, that nothing takes place save according to his appointment; that received into his favour, and entrusted to the care of his angels neither fire, nor water, nor sword, can do him harm, except in so far as God their master is pleased to permit. (John Calvin, Institues of the Christian Religion, 1.17.11.)
