Not so. The last time I knew the teaching of Jesus' death and resurrection by Jehovah's Witnesses is that the human body of Jesus was reduced to ashes (it disappeared) and he was resurrected as a spirit. Spirits of God are able to be seen in human form, like the angels that Abraham entertained.I've never heard the distinction being discussed by Jws so I'm guessing it's not a matter of importance. However I would say in my opinion that it was Jesus original body.
Genesis 18:1-16
