That the bible alone is not sufficient
They believe that reading the bible alone will lead to darkness and heresy. God's Word is not enough for them. They have incorporated outside teachings and in fact have their own bible called the 'New World Translation' or 'NWT'. Greek scholar's universally reject the NWT, calling it biased and innacurate. You may be shocked to know that the NWT used by Jehovah Witness's has about 20 verses CHANGED to suit their teachings!
THE BIBLE USED BY JEHOVAH WITNESS' HAS MANY VERSES CHANGED! THEY HAVE CHANGED VERSES THAT DONT AGREE WITH THEIR VIEWS!! THEY DO NOT AGREE WITH GOD's WORD!!!
The fact that they have their own bible should ring alarm bells.

That Jesus was not bodily resurrected
Jesus was resurrected in the flesh on the third day and appeared to many;
(Luke 24:36-40)
And while they were telling these things, He Himself stood in their midst.
But they were startled and thought they were seeing a spirit.
And He said to them, "Why are you troubled, and why do doubts arise in your hearts?"
See My hand and My feet, that it is I Myself; touch Me and see, for a spirit does not have flesh and bones as you see that I have
