This text in John 16:8-11. You can find the Greek here.
when the Spirit is come to you,
he will show the world how wrong it was
and about righteousness,
and about judgment.
proved because they refused to believe in me;
because I go to my Father, and you see me no more;
because the prince of this world is judged.
What does it mean?
I can explain some words. He called the Spirit paraclete. In Latin, this would be advocate, or builder – one who strengthens us. Such words must seem almost meaningless. Someone said to me once that my letters were good grammar but they could not understand their meaning.
I will try to explain more: the world, and I include you and me, does not understand why Jesus was crucified. The world does not believe. But when the Spirit comes to you, that coming will show you three things were true.
First, that God is love, but we, beloved, could not accept the love or the lover. This is the truth about sin. You don’t know love until the Spirit informs you. What a difficulty! You don’t believe so you don’t know. But how will you know since you must believe to know?
Secondly, that love is vindicated even when it is rejected. Why would we be happy that we see him no more? Because the presence of the Spirit changes everything. We know in this case that there is a new thing in the world and we are changed by it. This is the truth about right and wrong.
That brings me to the third point, that how we judge in the world is changed. We see him no more, but we know him through the same power that raised him from the dead. By this, we know that we are not condemned, but accepted. This is the truth about judgment.
(postscript) We could and must relate paracletos to the Hebrew for comforter or consolation. So Isaiah 40:1 – Comfort ye, comfort ye my people, says your God
παρακαλεῖτε παρακαλεῖτε τὸν λαόν μου λέγει ὁ θεός
נַחֲמוּ נַחֲמוּ עַמִּי יֹאמַר אֱלֹהֵיכֶֽם
