Of not troubling ourselves about outward things
“My Son, in many things it behoveth thee to be ignorant, and to esteem thyself as one dead upon the earth, and as one to whom the whole world is crucified. Many things also thou must pass by with deaf ear, and must rather think upon those things which belong unto thy peace. It is more profitable to turn away thine eyes from those things that displease, and to leave each man to his own opinion, than to give thyself to discourses of strife. If thou stand well with God and hast His judgment in thy mind, thou wilt verily easily bear to be as one conquered.”
2. O Lord, to what have we come? Behold a temporal loss is mourned over; for a trifling gain we labour and hurry; and spiritual loss passeth away into forgetfulness, and we rarely recover it. That which profiteth little or nothing is looked after, and that which is altogether necessary is negligently passed by; because the whole man slideth away to outward things, and unless he quickly recovereth himself in outward things he willingly lieth down.
