1 John 2:1 My little children, I am writing these things to you so
that you may not sin. And if anyone sins, we have an Advocate
(paraclete) with the Father, Jesus Christ the righteous.
Jesus told the disciples he would send a helper and that they would see HIM (Jesus) again - after he has risen to the Father, he would return in spirit.
John 16:16 A little while, and you will no longer see Me; and again a
little while, and you will see Me. 17 Some of His disciples then said
to one another, “What is this thing He is telling us, ‘A little while,
and you will not see Me; and again a little while, and you will see
Me’; and, ‘because I go to the Father’
No mention of the spirit in these passages - the spirit is the means for Jesus and the Father to dwell in us.
John 14:23 Jesus answered and said to him, “If anyone loves Me, he
will keep My word; and My Father will love him, and We will come to
him and make Our abode with him.
Jesus IS the Paraclete!
Not only is Jesus the paraclete or comforter, he is the original comforter.
And I will pray the Father, and He will give you another helper, that he may abide with you forever — the Spirit of truth. John 14:16
As Jesus is the one speaking, he is sending another. Who is the first? Jesus.
A paraclete is spoken of in 2 Cor 1 TEN times and refers to God. He comforts through Jesus v5. Again, no mention of the spirit from Paul as he expresses that it is God - through Christ, that our comfort will come. As Jesus does northing of himself, what he does do, is God through him. Jesus is the comforter by the power, love and wisdom of God through him.
Blessed be the God and Father of our Lord Jesus Christ, the Father of mercies and God of all comfort, who comforts us in all our affliction so that we will be able to comfort those who are in any affliction with the comfort with which we ourselves are comforted by God. 5 For just as the sufferings of Christ are ours in abundance, so also our comfort is abundant through Christ.
Now when Jesus goes away to the Father, he remains with them as the comforter through the spirit which comes from the Father through Jesus.
