My book You Will Live Forever: Religion, Science And Reincarnation, bases my argument for eternal life for all on three premises: 1. The first is not often heard, the argument called non-dualism. This means that god is everything, all spirit and matter. Therefore, since god is eternal, all human beings and animals also are eternal. 2. God is love, a much more frequently heard reason for believing in reincarnation, but a good one. 3. If god is all-powerful, all-loving and we're parts of god, god surely saves us all by reincarnation. I have four more reasons why I believe god grants us reincarnation: 1. Without this method of saving and reusing us, Earth would be unspeakably tragic in view of our being able to think, to love, to hope and to dream. 2. Earth would be drastically unfair and unequal, with billions of human beings never having opportunities for escape from poverty, disease, physical handicaps and lack of education. 3. God would be extremely wasteful if a new spirit had to be created every time a new one is needed. 4. Faith in reincarnation relieves us of great sadness for we believe we and our loved ones are reunited in heaven, and at death we don't have to say farewell to Earth.
