John 14:16-17 And I will ask the Father, and He will give you another Advocate to be with you forever — 17 the Spirit of truth. The world cannot receive Him, because it neither sees Him nor knows Him. But you do know Him, for He abides with you and He will be in you.
John 14:26-27 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 told 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; do not be afraid.
John 1:32-34 Then John testified, “I saw the Spirit descending from heaven like a dove and resting on Him. 33 I myself did not know Him, but the One who sent me to baptize with water told me, ‘The man on whom you see the Spirit descend and rest is He who will baptize with the Holy Spirit.’ 34 I have seen and testified that this is the Son of God.”
Acts 1:8-9 But you will receive power when the Holy Spirit comes upon you, and you will be My witnesses in Jerusalem, and in all Judea and Samaria, and to the ends of the earth. 9 After He had said this, they watched as He was taken up, and a cloud hid Him from their sight.
