I press on toward the goal for the prize of the upward call of God in Christ Jesus.
See how great a distance this is that must be run over! See how great an ascent! Thither we must fly up with the wings of the Spirit, otherwise it is impossible to surmount this height. Thither must we go with the body, for it is allowed. “For our citizenship is in heaven” (Phil. iii. 20), there is the prize; seest thou the runners, how they live by rule, how they touch nothing that relaxes their strength, how they exercise themselves every day in the palaestra, under a master, and by rule? Imitate them, or rather exhibit even greater eagerness, for the prizes are not equal: many are those who would hinder you; live by rule: many are the things which relax your strength; make its feet agile: for it is possible so to do, it comes not naturally, but by our will. Let us bring it to lightness, lest our swiftness of foot be hindered by the weight of other things. Teach thy feet to be sure, for there are many slippery places, and if thou fallest, straightway thou losest much. But yet if thou fall, rise up again. Even thus mayst thou obtain the victory. Never attempt slippery things, and thou wilt not fall; walk upon firm ground, up with thy head, up with thine eyes; these commands the trainers give to those who run. Thus thy strength is supported; but if thou stoopest downward, thou fallest, thou art relaxed. Look upward, where the prize is; the sight of the prize increaseth the determination of our will. The hope of taking it suffereth not to perceive the toils, it maketh the distance appear short. And what is this prize? No palm branch; but what? The kingdom of heaven, everlasting rest, glory together with Christ, the inheritance, brotherhood, ten thousand good things, which it is impossible to name. – St. John Chrysostom, Homily XII on the Epistle to the Philippians
