Who Is the Holy Spirit?

Most people today believe that we live in a closed, mechanistic universe, that is, a universe that functions from day to day according to certain physical forces and causes. Classical Christianity has taken a very different view, teaching that God is the primary cause of the universe, but also that He is the primary cause of everything in the universe and of everything that happens in the universe and in short, that God, not mechanistic forces, is the primary cause of what is and what happens.
