Jesus said that He came in His father's name--what was His father's name? Jesus (Jehovah has become our salvation).
"...but I know you, that you do not have the love of God in yourselves. 43"I have come in My Father's name, and you do not receive Me; if another comes in his own name, you will receive him. (The ANTICHRIST)44"How can you believe, when you receive glory from one another and you do not seek the glory that is from the one and only God?…"John 5:43
Again--Jesus said there is only ONE GOD!! Not Two not Three.
Jesus said that he would send the Comforter or the Holy Ghost in His name--what name? Jesus name.
16And I will pray the Father, and he shall give you another Comforter, that he may abide with you for ever; 17Even the Spirit of truth; whom the world cannot receive, because it seeth him not, neither knoweth him: but ye know him; for he dwelleth with you, (JESUS DWELT WITH THEM) and shall be in you (THE HOLY GHOST WILL DWELL IN THEM)
18I will not leave you comfortless: I will come to you. (JESUS SAID THAT HE WOULD COME UNTO THEM-JESUS IS THE HOLY GHOST) 19Yet a little while, and the world seeth me no more; but ye see me: because I live, ye shall live also. 20At that day ye shall know that I am in my Father, and ye in me, and I in you (SAME SPIRIT THAT DWELED IN JESUS WILL DWELL IN YOU AFTER THAT YOU RECEVIE THE HOLY GHOST!)
It is all the same NAME because it is the same GOD --there is no division in GOD.
