a Bible passage
9. faith—not of doctrines, but of miracles: confidence in God, by the impulse of His Spirit, that He would enable them to perform any required miracle (compare 1Co 13:2; Mr 11:23; Jas 5:15). Its nature, or principle, is the same as that of saving faith, namely, reliance on God; the producing cause, also, in the same,' namely, a power altogether supernatural (Eph 1:19, 20). But the objects of faith differ respectively. Hence, we see, saving faith does not save by its instrinsic merit, but by the merits of Him who is the object of it.
healing—Greek plural, "healings"; referring to different kinds of disease which need different kinds of healing (Mt 10:1).
