John 14: 15-21
15 ‘If you love me, you will keep my commandments. 16And I will ask the Father, and he will give you another Advocate, to be with you for ever.17This is the Spirit of truth, whom the world cannot receive, because it neither sees him nor knows him. You know him, because he abides with you, and he will be in you.
18 ‘I will not leave you orphaned; I am coming to you. 19In a little while the world will no longer see me, but you will see me; because I live, you also will live. 20On that day you will know that I am in my Father, and you in me, and I in you. 21They who have my commandments and keep them are those who love me; and those who love me will be loved by my Father, and I will love them and reveal myself to them.’
