BUT I ALREADY HAVE THE HOLY SPIRIT?

Yes, every son of God in Christ is indwelt by the Holy Spirit. Yet some are not even aware of Him, to even talk of relating with Him. Yet still, (like I was) there are many who though have received His embrace, became filled with Him, speaking with heavenly utterance, operating in His gifts, do not have a practical relationship with Him. So, it is not uncommon to have Him in you and still function in religion. What makes the difference is when you realize His personhood, His God-ness and fully appreciate His role in you beyond just a Pentecostal or Charismatic experience. From today, intentionally relate daily with Him as a person in you, not a 'force' to stir up in prayer for power or miracles. Greet Him, talk with Him, listen to Him, worship Him, rejoice with Him etc. The more you do this, the more conscious you become of Him and that opens the chapters into His deeper chambers that will result in that practical relationship with the Godhead that I am talking about and will continue next month.
