John 14:15-21 Revised Standard Version (RSV)
The Promise of the Holy Spirit
15 “If you love me, you will keep my commandments. 16 And I will pray the Father, and he will give you another Counselor, to be with you for ever, 17 even 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.
18 “I will not leave you desolate; 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 He who has my commandments and keeps them, he it is who loves me; and he who loves me will be loved by my Father, and I will love him and manifest myself to him.”
