Why do you think we have to die a physical death? Why can't we change our mortal bodies to immortal bodies now. Mind over matter. Jesus said "I am the resurrection, though a man die yet shall he live. But he that lives and believes in me (what he taught) shall never die." Why do we accept physical death so easily? In the bible it tells about Enoch not seeing death because God took him. We, I believe, can manifest the same type of body Jesus had after he resurrected. He overcame death and manifested immortality.
We were given dominion over all the works of God. That includes our bodies. If we accept physical death it will surely come. As a man believes in his heart so he is. Be it done to you according to your faith or belief. If God wills death than God is not a God of life. Forgive my rambleing, but I think we limit ourselves and the power that is in us.
