My reason for confining the query to the grace of faith, is from the difficulty that I find in ascertaining the truth of my love, repentance, opposition to sin, and even my obedience itself, unless all of these appear to flow in me from faith in Christ as their principle. "Another reason is, in examining myself as to my state or frame, I find that if my conscience is mistaken or ignorant of the rule of God's word, then all the conclusions resulting from comparing my heart and ways with it, must be wrong and uncertain in the same degree as my conscience is erroneous, and its testimony false.
