“The grace of God is to God himself as sunlight is to the sun — a means and a way leading us to the latter. It therefore shines within us in a simple, one-fold way and makes us deiform, that is, like God. This likeness constantly sinks away, dying in God and becoming and remaining one with him, for charity makes us become one with God and causes us to remain living in union with him.”

The Tragic Sense of Life (1913), VIII : From God to God
Context: And He is the God of the humble, for in the words of the Apostle, God chose the foolish things of the world to confound the wise and the weak things of the world to confound the things which are mighty (I Cor. i. 27) And God is in each of us in the measure in which one feels Him and loves Him. "If of two men," says Kierkegaard, "one prays to the true God without sincerity of heart, and the other prays to the an idol with all the passion of an infinite yearning, it is the first who really prays to the idol, while the second really prays to God." It would be better to say that the true God is He to whom man truly prays and whom man truly desires. And there may even be a truer revelation in superstition itself than in theology.

XIV. In what sense, though the Gods never change, they are said to be made angry and appeased.
On the Gods and the Cosmos
Context: If any one thinks the doctrine of the unchangeableness of the Gods is reasonable and true, and then wonders how it is that they rejoice in the good and reject the bad, are angry with sinners and become propitious when appeased, the answer is as follows: God does not rejoice — for that which rejoices also grieves; nor is he angered — for to be angered is a passion; nor is he appeased by gifts — if he were, he would be conquered by pleasure.
It is impious to suppose that the divine is affected for good or ill by human things. The Gods are always good and always do good and never harm, being always in the same state and like themselves. The truth simply is that, when we are good, we are joined to the Gods by our likeness to live according to virtue we cling to the Gods, and when we become evil we make the Gods our enemies — not because they are angered against us, but because our sins prevent the light of the Gods from shining upon us, and put us in communion with spirits of punishment. And if by prayers and sacrifices we find forgiveness of sins, we do not appease or change the Gods, but by what we do and by our turning toward the divine we heal our own badness and so enjoy again the goodness of the Gods. To say that God turns away from the evil is like saying that the sun hides himself from the blind.
