One of the common sense beliefs that Jehovah's Witnesses got right which made it easy to eliminate most other religions as false but is worth mentioning for other Bible believers visiting who don't already know, is that the use of the cross or any other symbol is wrong as it is idolatry.

“My beloved ones, flee from idolatry.” - 1 Cor. 10:14 (An idol is an image or symbol that is an object of intense devotion, veneration, or worship.)

“You shall not make yourself a carved image or any likeness of anything in heaven or on earth beneath or in the waters under the earth; you shall not bow down to them or serve them.” - Ex. 20:4, 5 (Notice that God commanded that his people not even make an image before which people would bow down.)

But where the Watchtower Organization gets it wrong is when they try to show all other religions wrong by saying that Jesus died on a Cross, and they are the only ones who have it right that he died on a stake. But did he? Let's look at the facts:

• "Consequently the other disciples would say to him: “We have seen the Lord!” But he said to them: “Unless I see in his hands the print of the nails and stick my finger into the print of the nails and stick my hand into his side, I will certainly not believe.”" - The Watchtower organization pictures Jesus as having ONE NAIL through both hands, but the use of the plurals here tells us that there were likely nails in each of his hands, which leans towards a cross.

• An Austrian radiologist experimented with medical students by hanging them by their wrists with their hands directly above their heads (much like the Watchtower pictures Jesus on a stake). In minutes, the students became pale, their lung capacity dropped, blood pressure decreased and the pulse rate increased. It was concluded that inability to breathe would occur in about six minutes. But it was also discovered that if students were hung by hands outstretched to the side at 60-70 degrees, they would have no trouble breathing for hours on end. Since Luke 23:44 and Matthew 27:45,46 show that Christ was on the cross for about three hours, the evidence points again to death on a traditional cross.

• Archaeological and Historical evidence all points towards a cross, see references below for in-depth information on this.

On the left below, you can see that in the book Reasoning From the Scriptures Jehovah's Witnesses quote from The Imperial Bible-Dictionary to prove that Jesus died on a cross. On the right, you can see the actual page showing the exact opposite was actually implied, and yet omitted by The Organization.
