Why would people have no sin if Jesus hadn’t come and
spoken to them?
They wouldn't have known how sinful they were. John 1:5 refers to Jesus
coming into the world as "the light shines in the darkness."
Imagine a group of people in a dark room who are covered in filth but think
they are
clean, until someone switches on the light. Until the light shines, they could
claim ignorance of their filthy condition and even remain in them. But once the light shines, "they have no excuse
for their sin" (John 15:22).
Is it possible to hate Jesus without hating God the
Father?
"He who hates Me hates My Father also" (John
15:23).
Why would people have no sin if Jesus hadn’t "done
among them the works which no one else did" (John 15:24)?
Those miraculous works proved that Jesus is God who has co-equal status
with God the "Father" (John 15:24) and has
the right to 'switch on the light' (see above) and address their sin.
What were some of His miracles "which no one else
did" (John 15:24)?
He opened the eyes of the blind (see
Jesus heals the blind man), fed a large crowd with a boy's meal
(see
Jesus feeds five thousand), walked on water (see
Jesus king), raised the dead to life (see
Lazarus, come forth!), etc., and would soon rise from the dead
Himself (see
resurrection of Jesus).
Who is Jesus referring to as "the Helper" and the "Spirit of truth" in John 15:26?
God the
Holy Spirit.
Of whom will He testify?
Jesus said, "He will testify of Me" (John 15:26).
This is important to bear in mind when deciphering whether something is
or isn't the work of the Holy Spirit.
The Holy
Spirit will testify of Jesus, which means He won't contradict Jesus, whom
John 1:1 calls the Word of God.
Anything that contradicts the Bible isn't of the Holy Spirit.
When did Jesus send the Holy Spirit "from the
Father" (John 15:26)?
At Pentecost (see
Acts 2).
