To know God as the sovereign disposer of all good, inviting us to present our requests, and yet not to approach or ask of him, were so far from availing us, that it were just as if one told of a treasure were to allow it to remain buried in the ground.
John CalvinLet this point therefore stand: that those whom the Holy Spirit has inwardly taught truly rest upon Scripture, and that Scripture itself is self-authenticated. . . . Therefore, illumined by his power, we believe neither by our own nor by any one else's judgment that Scripture is from God; but above human judgment we affirm with utter certainty (just as if we were gazing upon the majesty of God himself) that it has flowed to us from the very mouth of God by the ministry of men.
John Calvin
