It is desirable, that these views and principles should be remembered. They aid in justifying the representations of Scripture, which every where and most emphatically ascribe man’s spiritual restoration to faith. Nor can any other principle, considered as standing first and standing alone, take its place. Even the principle of love, noble and divine as it is, could not unite the soul to God, and could not even be pleasing to God, without faith as its antecedent and basis. In the full possession of faith, we at once enter into harmony with God, and we necessarily exercise, on their appropriate occasions, all those affections which are desirable. By a law of its own nature it propagates every thing else from its own bosom. Having once come into existence under the divine inspiration, it may be said instrumentally and in the natural filiation of the mental exercises, to make all, to secure all. But without faith, whatever else he may have, man is left of God and left of happiness.
