No religion that has ever visited it's ugly face on this planet has ever been able to demonstrate the validity of their after-life promises and/or expectations...albeit that they reluctantly must admit that all living things cease to have a physical existence. How many of the "anointed" who have died, even those whom you might have very personally known, have ever bothered themselves to come back to you and said "Here I am!!!!" I've known dozens of them, some as comrades, and nary a word. So, to the point: I can talk out of my orifices all I want about what the future holds, and yet not one person on this planet (including Jesus Holy Christ Himself);has ever demonstrated, beyond any doubt, that there is anything other than Death awaiting the Human Organism.
Elijah was taken up in a whirlwind. He didn't even experience a "physical" death. Where do you think he went? According to God's word, directly to heaven. 2 Kings 2:1 says, "And it came to pass, when the LORD would take up Elijah into heaven by a whirlwind , that Elijah went with Elisha from Gilgal."
Jesus rose from the dead and there's an empty grave to prove it. The scriptures (the very words of God) testify to the resurrection, and God does not lie.
In Matthew 22:29-32 Jesus says, " Jesus answered and said unto them, Ye do err, not knowing the scriptures, nor the power of God. For in the resurrection they neither marry, nor are given in marriage, but are as the angels of God in heaven. But as touching the resurrection of the dead, have ye not read that which was spoken unto you by God, saying, I am the God of Abraham , and the God of Isaac, and the God of Jacob? God is not the God of the dead, but of the living. " So, first of all, if Jesus said there is a resurrection when there is not, then he lied and was not without sin and hence, able to be the sacrifice for our sins. Secondly, since God is not the God of the dead, Abraham, Isaac, and Jacob are obviously alive though they died physically.
Jesus was not the only one to rise from the dead. In Matthew 27:52,53 it says, " And the graves were opened; and many bodies of the saints which slept arose, And came out of the graves after his resurrection, and went into the holy city, and appeared unto many."
In the scriptures, we read of an account where Moses and Elijah appeared and spoke with Jesus. Mark 9:4,5 says, " And there appeared unto them Elias with Moses: and they were talking with Jesus. And Peter answered and said to Jesus, Master, it is good for us to be here: and let us make three tabernacles; one for thee, and one for Moses, and one for Elias." I suppose then, Moses and Elias (Elijah) are both quite alive though they physically died.
1 Corintians 15:12-14 Now if Christ be preached that he rose from the dead , how say some among you that there is no resurrection of the dead ? But if there be no resurrection of the dead, then is Christ not risen: And if Christ be not risen, then is our preaching vain, and your faith is also vain.
Beside this, the Watchtower belief that the soul is not separate from the body (and dies with the body) is erronous. The scriptures teach differently.
