So commit yourself confidently and without hesitation, all that you are, and everything else, individually and in general, to the unfailing and totally reliable providence of God, in silence and in peace, and he will fight for you. He will liberate you and comfort you more fully, more effectively and more satisfactorily than if you were to dream about it all the time, day and night, and were to cast around frantically all over the place with the futile and confused thoughts of your mind in bondage, nor will you wear out your mind and body, wasting your time, and stupidly and pointlessly exhausting your strength.
–Saint Albert the Great (c.1206-1280)
