The Instructor 1.9.88

He confesses that judging and doing good belong to the same power; for the authority over both together is the judgment of the just one, separating opposites. The same God is just and good, the one who truly is God, who himself is all things, and all things are himself, because he himself is God, the only God. As a mirror is not bad to an ugly man because it shows him as he is, and as a physician is not bad to a sick man when he tells him of his fever (for the physician is not the cause of the fever, but its detector), so neither is the one who reproves ill-disposed toward one sick in soul; for he does not put the offenses there, but points out the sins that are present, to turn us from similar practices. So God is good in himself, and just for our sake, and this because he is good. He shows us his justice through his own Word from there above, from where he became Father. For before he became Creator he was God, he was good; and for this reason he willed to be both Maker and Father. The relation of that love became the beginning of justice, as he makes his sun shine and sends down his Son. And the Son first proclaimed the good justice from heaven, saying, “No one knew the Son except the Father, nor the Father except the Son.” This mutually balanced knowledge is a symbol of primal, equal justice. Then justice came down to human beings, both in letter and in body, in the law and in the Word, constraining humanity to saving repentance; for it was good. But you do not obey God: blame yourself for bringing the judge upon you.
