Who is the Holy Spirit? The Holy Spirit is a person just like God and Jesus. He is a part of the Godhead or the Trinity; all 3 persons working together as one. The Holy Spirit is a Gentleman and He will never force himself upon you. The Holy Spirit will come inside and use you and work through you ONLY if you allow him to. You can say no at any time. He will be sad, but He will never force himself upon you. If we keep saying no to Him, then He becomes Grieved. When He becomes grieved there can be consequences.
