The person with a good and sold faith should never refer to “all that happens” as God’s will, and no one should flatter himself by saying that “nothing happens apart from what He allows,” as if to say that there is nothing that we, in our own power, cannot do. If this were the case—if everything that happens were God’s will—then sin would be excused. That way of thinking would lead to the destruction of our way of life (nay) and even of God Himself—if it can be said that He makes happen by His own will things that He does not will, or if there is, in fact, nothing that He doesn’t will. . . . Accordingly, we should not blame “God’s will” for those things that we ourselves choose.
Tertullian, De exortatione castitatis 2.2,4
