John 14:15-21

15 If you love me, keep my commandments.  16 I will pray to the Father, and he will give you another Counselor, that he may be with you forever,--  17 the Spirit of truth, whom the world can't receive; for it doesn't see him, neither knows him. You know him, for he lives with you, and will be in you.  18 I will not leave you orphans. I will come to you.  19 Yet a little while, and the world will see me no more; but you will see me. Because I live, you will live also.  20 In that day you will know that I am in my Father, and you in me, and I in you.  21 One who has my commandments, and keeps them, that person is one who loves me. One who loves me will be loved by my Father, and I will love him, and will reveal myself to him.”

John 16:7-11

7 Nevertheless I tell you the truth: It is to your advantage that I go away, for if I don't go away, the Counselor won't come to you. But if I go, I will send him to you.  8 When he has come, he will convict the world about sin, about righteousness, and about judgment;  9 about sin, because they don't believe in me;  10 about righteousness, because I am going to my Father, and you won't see me any more;  11 about judgment, because the prince of this world has been judged.
