The SPIRIT OF TRUTH: the world cannot accept Him, because it neither sees Him nor knows Him, but you know Him, for He lives with you and will be in you. John 14:17.
And when He (the Holy Spirit) comes, He will convict the world of its sin, and of God’s righteousness, and of the coming judgment. The world’s sin is that it refuses to believe in me (Jesus).John 16:8-9
