You (God) have not only commanded continence, that is, from what things we are to restrain our love, but also justice, that is, on what we are to bestow our love.
True happiness is to rejoice in the truth, for to rejoice in the truth is to rejoice in You, O God, who are the truth... Those who think that there is another kind of happiness look for joy elsewhere, but theirs is not true joy.
I have read in Plato and Cicero sayings that are wise and very beautiful; but I have never read in either of them: Come unto me all ye that labor and are heavy laden.
He who commends the nature of the soul as the supreme good, and condemns the nature of the flesh as evil, at once both carnally desires the soul, and carnally flies the flesh, because he feels thus from human vanity, not from divine truth.
Often a non-Christian knows something about the earth, the heavens, and the other parts of the world, about the motions and orbits of the stars and even their sizes and distances... and this knowledge he holds with certainty from reason and experience. It is thus offensive and disgraceful for an unbeliever to hear a Christian talk nonsense about such things, claiming that what he is saying is based in Scripture. We should do all that we can to avoid such an embarrassing situation, which people see as ignorance in the Christian and laugh to scorn.
For, were it not good that evil things should also exist, the omnipotent God would almost certainly not allow evil to be, since beyond doubt it is just as easy for Him not to allow what He does not will, as for Him to do what He will.
