...there is no faith without God's word, for of his faithfulness we cannot be convinced, until he has spoken. And this of itself is abundantly sufficient to confute the fiction of the sophists respecting implicit faith; for we must ever hold that there is a mutual relation between God's word and our faith. But as faith is founded chiefly, according to what has been already said, on the benevolence or kindness of God, it is not every word, though coming from his mouth, that is sufficient; but a promise is necessary as an evidence of his favor. Hence Sarah is said to have counted God faithful who had promised. True faith then is that which hears God speaking and rests on his promise.
