John 14:15-17 New Revised Standard Version (NRSV)
The Promise of the Holy Spirit
15 “If you love me, you will keep[a] my commandments. 16 And I will ask the Father, and he will give you another Advocate,[b] to be with you forever. 17 This 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[c] you.
John 14:25-27 New Revised Standard Version (NRSV)
25 “I have said these things to you while I am still with you. 26 But the Advocate,[a] the Holy Spirit, whom the Father will send in my name, will teach you everything, and remind you of all that I have said to you. 27 Peace I leave with you; my peace I give to you. I do not give to you as the world gives. Do not let your hearts be troubled, and do not let them be afraid.
