That Portions of the World are Not to Be Loved; But that God, Their Author, is Immutable, and His Word Eternal
16 Be not foolish, O my soul, and deaden not the ear of your heart with the tumult of your folly. Hearken also. The word itself invokes you to return; and there is the place of rest imperturbable, where love is not abandoned if itself abandons not. Behold, these things pass away, that others may succeed them, and so this lower universe be made complete in all its parts. But do I depart anywhere, says the word of God? There fix your habitation. There commit whatsoever you have thence, O my soul; at all events now you are tired out with deceits. Commit to truth whatsoever you have from the truth, and nothing shall you lose; and your decay shall flourish again, and all your diseases be healed, and your perishable parts shall be reformed and renovated, and drawn together to you; nor shall they put you down where themselves descend, but they shall abide with you, and continue for ever before God, who abides and continues for ever.
17. Why, then, be perverse and follow your flesh? Rather let it be converted and follow you. Whatever by her you feel, is but in part; and the whole, of which these are portions, you are ignorant of, and yet they delight you. But had the sense of your flesh been capable of comprehending the whole, and not itself also, for your punishment, been justly limited to a portion of the whole, you would that whatsoever exists at the present time should pass away, that so the whole might please you more. For what we speak, also by the same sense of the flesh you hear, and yet wouldest not thou that the syllables should stay, but fly away, that others may come, and the whole be heard. Thus it is always, when any single thing is composed of many, all of which exist not together, all together would delight more than they do simply could all be perceived at once. But far better than these is He who made all; and He is our God, and He passes not away, for there is nothing to succeed Him. If bodies please you, praise God for them, and turn back your love upon their Creator, lest in those things which please you you displease.
