"The Testimony 0f Jesus", is declaired and affirmed statments in which facts of Him have already been established.

By public indications of evidance.
1.) - By His word.
2.) - By our faith.
3). - By spiritual experience.

But, "The Spirit 0f Prophecy" predicts Jesus in the lives of mankind by HIS TESTIMONY. "The Testimony 0f Jesus".

Not the testimonials from mankind about Jesus.
Which is "by our faith", or "spiritual experience".

The angel told John, he is a servant of John's.
And John's brethern who, "Have The Testimony Of Jesus".
Rev.19:10

The angel didn't say he is of John's brethern who gives testimonies of Jesus through his faith in God's word.

We, "have the testimony of Jesus".
Because Jesus gave it to us.

"For the testimony of Jesus is the spirit of prophecy"Rev.19:10

Our testimony of Jesus is not the spirit of prophecy.

"The testimony of Jesus is the spirit of prophecy". - Rev.19:10

Our testimony of Jesus is a witness.
Not the spirit of prophecy.

Jesus said, the words I speak to you they are spirit
and they are life. John 6:63

The spirit of prophecy is Jesus' testimony.

Having the testimony of Jesus.
Does not mean we have the spirit of prophecy.

"The testimony of Jesus IS THE spirit of prophecy".

His testimony IS THE spirit of prophecy.
Not our testimonial of Him.
Our testimonal of Him is through faith in His word
or in spiritual experiences.

Those who,
"...Keep The Words Of This Book..." Rev.22:9 - Rev.22:18,19

Will,
"...Have, or Give, The Testimony Of Jesus..." - Rev.19:10

for we are to be witnesses of Him.

We do not have His Spirit 0f Prophecy.
