Throughout Galatians, Paul has warned us that we cannot find eternal life through obeying the Law. Nor can we find it through following the desires of our flesh. Instead, he urges us to walk in step with the Holy Spirit, because only the Spirit can make us truly alive. But who is the Holy Spirit? What does He do, and how can we relate to Him? How can we pursue the life that God promises to us, through the power of the Holy Spirit?
