In case we miss the answer we have been looking for since yesterday, Paul gives us the answer twenty-one times in Romans 8: SPIRIT.
Paul left us with a defense of Law; it is not the root of our problem. But Law is also not the answer to our problem, because it lacks the power to move us past our own powerlessness. What we need is a power outside of ourselves. And this is exactly what God brings: the Holy Spirit of God living within us (8:9).
The spirit comes alongside and helps us in our weakness. (8:26)
Maybe you grew up as I did in a religious tradition too scared to talk about the Holy Spirit lest we be labeled as charismatic, as if that were some great sin. However, when we neglect the Spirit we are left only with ourselves and we are back in the middle of the mess of Romans 7.
Christians are called to listen with attentive minds and hearts to the Spirit of God within us (8:5-6). This Spirit will guide and empower the children of God to live in accordance of God’s wishes, as the Spirit is the first piece of the new life already given to us (8:14, 23, 26-27). All that God intended in the Law becomes possible when we “live according to the Spirit” (8:4).
