Securely locating the doctrine of the Spirit inside the doctrine of the Trinity automatically grants you the next three things you should know.

Nor is the Holy Spirit a slice of God, one third of God, or part of a team that adds up to be God. He is one of the persons who fully possesses the entirety of the divine essence.
