John 14: 16 & 17

16 And I will ask the Father and He will give you another Advocate to help you and be with you forever- the Spirit of Truth.

I’ve just reassured you that you can ask me for anything in my name. In fact, I’ve told you twice now that I will do for you whatever you ask that is consistent with my name (character, nature, purpose). I will not violate my integrity and forsake my plan in order to answer you. I am true to myself and my Father. It is for this reason that I bring you into alignment with myself so we are work together. You, the Father, the Advocate, and me - all on the same page – working for the same goal which is to glorify the Father.
In the same way that you ask me, I ask the Father. I ask in accordance with His glorious plan, too, which includes not leaving you alone or abandoned or forsaken. Quite to the contrary…..you will be accompanied by me in a new way….by the Holy Spirit of God.
The only way you can keep my commands is by the power of God and with His help anyway. This is why I am asking the Father to give you One who can help you. The Advocate, the Paraclete, the One who comes along side. My departure and return to Heaven is not detrimental but essential, because my leaving ushers in the opportunity for the Helper to come in my place. My leaving insures the coming of Another, the Spirit of Truth. I am the Way, the Truth, and the Life. Therefore, the embodiment of Truth will come to you as spirit. The Spirit of Truthfulness and Absolute Reality will abide with you.

17 The world cannot accept Him, because it neither sees Him or knows Him. But you know Him, for He lives with you and will be in you."

The world cannot accept or receive Him. Why? Because they do not recognize Him, they do not know who He is. Sadly, He is foreign to them, a stranger, and someone unfamiliar. They are blind and deaf, even though they’ve seen me and heard me, they still do not know who The Way-Truth-Life is or who the Spirit of Truth is. They believe the lie instead.
The world cannot accept Him because they do not belong to the One who is sending Him. You receive Him because you know the Father who is sending Him and have already believed in Him. If the world recognized the Father they would also know the One who comes from the Father.
But you do know Him. You already know Him because it is He who is with you even now. The Spirit of Truth and The Truth are One in the same. I am with you in body now but in a little while I will be with you in spirit. You will recognize me and welcome me. I will come to you and dwell in you.
This Advocate, the Spirit of Truth, will lead you in all truth. The truth about who I am and who the Father is. Because he will live inside you, He will enable you to know and understand more than if I remained here with you, on the outside of you. The Spirit reveals truth to you from the inside. Up till now truth has come to you from the outside. God is making a new covenant with you, a new and living Way. You will understand more after I have returned to the Father and the Holy Spirit will explain this to you.
