The longer one lives and the more one thinks about things, the surer one becomes that the supreme issue which governs everything between God and man is that of life. Our Scripture says here that life is a law, and it further says that that life is in the hands of the Holy Spirit - "the law of the Spirit of life...". A law is a fixed and established principle. It has potentialities. It means that, if you are adjusted to it and governed by it, certain results are inevitable; that the potentialities which it contains will most surely find expression when that law is established. So that, what we have here is, that the mark of things being of God the Holy Spirit is life. If anything is of God the Holy Spirit, it will live; its chief characteristic will be life. That is a law, an established principle. What is according to God lives, having God's own life in it, and that is, as a principle, a rule of guidance. It is a principle for the direction of the people of God.
