John 14:15-17, 26 "If you love me, you will keep my commandments. 16And I will ask the Father, and he will give you another Helper, to be with you forever, 17even the Spirit of truth, whom the world cannot receive, because it neither sees him nor knows him. You know him, for he dwells with you and will be in you.
26But the Helper, the Holy Spirit, whom the Father will send in my name, he will teach you all things and bring to your remembrance all that I have said to you.
