In this sermon on the third article of the Nicene Creed, Dr. Michael Horton examines the Holy Spirit as "the Lord and giver of life." Dr. Horton traces the Spirit's work through three stages: creation, redemption, and consummation, focusing on the recurring biblical image of the Spirit "brooding" or "hovering" over waters to bring forth life. He connects the Spirit's movement over the formless deep in Genesis 1:2 to the Spirit's overshadowing of Mary's womb and the Spirit's work in regenerating and sanctifying believers today. Drawing on patristic sources, Calvin, and Gerard Manley Hopkins' poem "God's Grandeur," this episode develops the theme that all of God's works flow "from the Father in the Son by the Spirit," with the Spirit consistently completing and perfecting what the Father speaks and the Son mediates.
