Who is the Holy Spirit? The third person of the Trinity has often been misunderstood resulting in some keeping Him at an arms length. In part one of this new series, Pastor Pete taught us who the Holy Spirit is and how we can strengthen our relationship with God by opening up our hearts to Him. The Holy Spirit is like a breath of fresh air. He is unseen, unpredictable, powerful and refreshing, and in order to not take Him for granted, we must let go of our fears and misperceptions and go all in.
