Jehovah's Witnesses believe that they should represent Jehovah God and that Jesus Christ is not God they believe that he is an incarnation not of the eternal glory of God but of actually the very first created being the Archangel Michael

Here's what happened with me to try to engage JW's in my neighborhood.  This is to encourage you to engage them in conversation to learn what they believe. And then you share the truth about the Trinity and that Jesus is God.
