In this verse the Lord Jesus says that when He departs then the Comforter will be sent to them:
"Nevertheless I tell you the truth; It is expedient for you that I go away: for if I go not away, the Comforter will not come unto you; but if I depart, I will send him unto you" (Jn.16:7).
I cannot believe that this verse is speaking of only "one" Person but instead two different Persons. Therefore, I cannot believe that the Lord Jesus is the Comforter, who is identified as the Holy Spirit.
There is only one Spirit.
Ephesians 4:4 There is one body, and one Spirit, even as ye are called in one hope of your calling;
1 Corinthians 12:11 But all these worketh that one and the selfsame Spirit, dividing to every man severally as he will.
That Spirit is Jesus.
John 14:18 I will not leave you comfortless: I will come to you.
Jesus said He will come unto men before John 16:7
John 16:7 says "He say to go away for the Holy Ghost to come to men"
John 7:37 ....If any man thirst, let him come unto me, and drink.
38 He that believeth on me, as the scripture hath said, out of his belly shall flow rivers of living water.
39 (But this spake he of the Spirit, which they that believe on him should receive: for the Holy Ghost was not yet given; because that Jesus was not yet glorified.)
Jesus is the name of the Holy Ghost.
John 14:26 But the Comforter, which is the Holy Ghost, whom the Father will send in my name......
The Holy Ghost is ONLY SENT in His name which is Jesus.
