I) 14:16-17, "And I will ask the Father, and he will give you another Counselor to be with you forever - the Spirit of truth, The world cannot accept him, because it neither sees him nor knows him. But you know him, for he lives with you and will be in you." 26,"But the Counselor, the Holy Spirit, whom the father will send in my name, will teach you all things and will remind you of everything I have said to you."
II) 15:26, "When the counselor comes, whom I will send to you form the Father, the Spirit of truth, who goes out form the Father, he will testify about me."
III) 16:13-15, "But when He, the Spirit of Truth, comes, he will guide you into all truth. He will not speak on his own; he will speak only what He hears, and he will tell you what is yet to come. He will bring glory to me by taking from what is mine and making it known to you. All that belongs to the Father is mine. That is why I said the Spirit will take from what is mine and make it known to you."
IV) 20:21-22 "Again Jesus said, 'peace be with you! As the Father has sent me, I am sending you.' And with that, he breathed on them and said, 'Receive the Holy Spirit. If you forgive anyone his sins, they are forgiven; if you do not forgive then, they are not forgiven."
