no sound nor saving faith. It is but a general faith. It is but a historical knowledge and cannot save the soul. He therefore that upon examination of his heart and life finds his faith to be such, let him not content himself but turn his general faith into a saving faith, which in this world will purify his heart and at the last day will save his soul. And this must every man the rather do because what knowledge or what other gifts of God soever any man has, without faith in Christ, all are nothing.
