1. If we fail in this, or come short of this perfection, by any guile of our hearts, by voluntary retaining any sweet morsel under our tongue, by keeping a knee for Baal, or a bow for Rimmon,—we walk not with God. It is sad to think how many lose all they do or have wrought by coming short in this perfection. One vile lust or other,—love of the world, pride, ambition, idleness, hardheartedness,—may lose all, spoil all; and men walk contrary to God when they think they walk most with him.
