When the evidences of Christianity are exhibited, an appeal is made to the reason of men for its truth; but all evidence and all argument would be perfectly futile, if reason were not permitted to judge of their force. This noble faculty was certainly given to man to be a guide in religion, as well as in other things. He possesses no other means by which he can form a judgment on any subject, or assent to any truth; and it would be no more absurd to talk of seeing without eyes, than of knowing any thing without reason.
