John 14:15-21 New International Version (NIV)

Jesus Promises the Holy Spirit

¹⁵ “If you love me, keep my commands. ¹⁶ And I will ask the Father, and he will give you another advocate to help you and be with you forever— ¹⁷ 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^[a] in you. ¹⁸ I will not leave you as orphans; I will come to you. ¹⁹ Before long, the world will not see me anymore, but you will see me. Because I live, you also will live. ²⁰ On that day you will realize that I am in my Father, and you are in me, and I am in you. ²¹ Whoever has my commands and keeps them is the one who loves me. The one who loves me will be loved by my Father, and I too will love them and show myself to them.”

John 14:26 New International Version (NIV)

²⁶ But the Advocate, 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.
