Let no one grumble here that God could have provided better for our salvation if he had forestalled Adam’s fall. Pious minds ought to loathe this objection, because it manifests inordinate curiosity. Furthermore, the matter has to do with the secret of predestination, which will be discussed later in its proper place [3.21-24]. Let us accordingly remember to impute our ruin to depravity of nature, in order that we may not accuse God himself, the Author of nature. True, this deadly wound clings to nature, but it is a very important question whether the would has been inflicted from outside or has been present from the beginning. Yet it is evident that the would was inflicted through sin. We have therefore no reason to complain except against ourselves. Scripture has diligently noted this fact. For Ecclesiastes says: “This I know, that God made man upright, but they have sought out many devices.” [Ch. 7:29.] Obviously, man’s ruin is to be ascribed to man alone; for he, having acquired righteousness by God’s kindness, has by his own folly sunk into vanity.
Institutes, 2.1.10
