In both Testaments, human life is represented as walking in a path or way. In harmony with this idea, we are exhorted to walk circumspectly, honestly, and soberly; and, according to the same usage, we are spoken of as walking in love and walking in light. All these various phrases indicate the course of human life. The way of destruction is represented as a broad way, in which many walk careless of their destination, while the way of life is narrow and strait and leads directly to God and eternal life. God's Word is spoken of as a lamp lighting our path. The path of God's people is lighted by the divine grace shining through the pages of the written Word; and so the earthly life, the daily experience, the whole course of a Christian's earthly existence, is marked out for him.—Robert Stuart MacArthur.
