And again He has said, "All sins shall be forgiven unto the sons of men, and blasphemies; but he that shall blaspheme against the Holy Spirit shall not have forgiveness, but is guilty of eternal sin.".
Also according to Mark: "All sins shall be forgiven, and blasphemies, to the sons of men; but whoever shall blaspheme against the Holy Spirit, it shall not be forgiven him, but he shall be guilty of eternal sin."
He is the subject, not the object, of hallowing, apportioning, participating, filling, sustaining. We share in him; he shares in nothing. He is our inheritance, he is glorified, counted together with Father and Son. He is a dire warning to us, the “finger of God.” The Spirit is, like God, a “fire.” This means that the Holy Spirit is of the same essential nature as the Father. The Spirit is the very One who created us and creates us anew through baptism and resurrection. The Spirit knows all things, teaches all things, moves where and when and as strongly as he wills. He leads, speaks, sends, and separates those who are vexed and tempted. He reveals, illumines, gives life, or better said, he is himself light and life. He makes us his temple, he sanctifies, he makes us complete. He both goes before baptism and follows after it. All that the Godhead actively performs, the Spirit performs. Oration , On the Holy Spirit
