First of all, the Watchtower teaches that Jesus was re-created - not resurrected. His body was completely dissolved into gaseous form and a new body was created. This is not resurrection. Secondly, Jesus himself said HE would raise himself up. "Destroy this temple [His Body] and I will raise it up again in three days." The Watchtower ignores this scripture because this would confirm the deity of Jesus. Lastly, according to the Watchtower, Jesus is gone. He no longer exists. He is now Michael, the Archangel.
According to the WTS, "The man Jesus is dead, forever dead . . . " (Studies in the Scriptures, Vol. 5, 454). "We deny that he was raised in the flesh, and challenge any statement to that effect as being unscriptural" (Studies, Vol. 7, 57). Jesus’ fleshly body "was disposed of by Jehovah God, dissolved into its constitutive elements or atoms" (The Watchtower, 9-1-1953, 518). "In order to convince Thomas of who he was, he used a body with wound holes" (You Can Live Forever in Paradise on Earth, 145). He was raised as an invisible spirit creature, with no physical body (Reasoning From the Scriptures, 214-215).
However, according to Scripture, "If Christ has not been raised, your faith is in vain, and you are still in your sins" (1 Cor. 15:17). Jesus makes clear, even before death, that it is his body that will be raised up. He promises to raise up the temple once it is destroyed. "He was speaking about the temple of his body" (John 2:21). After he had risen, he gives the same testimony, "See my hands and my feet, that it is I myself; feel me and see, because a spirit does not have flesh and bones just as you behold that I have. . . . Do you have something there to eat?" (Luke 24:39, 41). Jesus insists that Thomas place his finger into his wounded side, so as to prove that he had indeed risen from the dead (John 20:27). There is no question that Jesus had truly risen from the dead. No Christian was under the impression that he was invisibly raised as Michael the Archangel, while God the Father dissolved his natural body. Such a presumption is without historical or scriptural warrant, and the "proof is in the pudding": Ask the JW to show you a Scripture verse which backs up the WTS’s assertion about God disposing of Jesus’ body. He can’t, because there isn’t one.
