John 14:15–18 (NLT) — 15 “If you love me, obey my commandments. 16 And I will ask the Father, and he will give you another Advocate, who will never leave you. 17 He is the Holy Spirit, who leads into all truth. The world cannot receive him, because it isn’t looking for him and doesn’t recognize him. But you know him, because he lives with you now and later will be in you. 18 No, I will not abandon you as orphans—I will come to you.
John 14:25–26 (NLT) — 25 I am telling you these things now while I am still with you. 26 But when the Father sends the Advocate as my representative—that is, the Holy Spirit—he will teach you everything and will remind you of everything I have told you.
John 15:26–27 (NLT) — 26 “But I will send you the Advocate—the Spirit of truth. He will come to you from the Father and will testify all about me. 27 And you must also testify about me because you have been with me from the beginning of my ministry. John 16:7–8 (NLT) — 7 But in fact, it is best for you that I go away, because if I don’t, the Advocate won’t come. If I do go away, then I will send him to you. 8 And when he comes, he will convict the world of its sin, and of God’s righteousness, and of the coming judgment.
