The Holy Spirit A B Simpson Chapter 12 – The Holy Spirit in the Body of Christ The Holy Ghost becomes the vital element of our new life. In Him we live, and move, and have our being. As the bird lives in the air, as the fish lives in the sea, as the flower lives on the sunshine, so we live in the element of the Holy Ghost; and, as we drink of His fullness, our life is maintained and grows into the maturity of Christ. This is the secret of being filled with the Spirit, and this is the source of fruitfulness and life.
