Origen

“ We must notice the remarks which Celsus next makes, when he says to us, that “faith, having taken possession of our minds, makes us yield the assent which we give to the doctrine of Jesus;” for of a truth it is faith which does produce such an assent. Observe, however, whether that faith does not of itself exhibit what is worthy of praise, seeing we entrust ourselves to the God who is over all, acknowledging our gratitude to Him who has led us to such a faith, and declaring that He could not have attempted or accomplished such a result without the divine assistance. ”
