And in connection with this view, we are not to be surprised that we find the Savior so often and so earnestly urging upon his followers the necessity of living in the same manner. He taught them, in various ways and at various times, that faith was the source of their inward life and power; and that by it they could overcome all difficulties, "removing even mountains." Discountenancing every other mode of living, he decidedly rebuked the disposition, originating in unbelief, to seek a sign, (that is to say, a striking and confirmatory manifestation of some kind, ) in addition to and in support of the simple declaration of God. "An evil and adulterous generation," he says," seeketh after a sign."
