a. Faith is "trust" in the sense of a grasping for the assurance of personal security in "salvation". Though there is much talk of "Christ" yet in fact everything centers in self and faith remains the means of satisfying personal insecurity.
b. Much the same. Faith is almost universally defined in the same terms as the Evangelicals.
c. Faith is such a deep heart-appreciation of God's sacrificial love that the believer is constrained to adopt Heaven's principle of self-denying love as the motivation of all his acts. (He does right because it is right, not from hope of reward or fear of punishment.) Conquers egocentricity and luke-warmness.
