8. The reason why all religion is of the life, is that after death everyone is his own life, for the life stays the same as it had been in this world, and undergoes no change. For an evil life cannot be converted into a good one, nor a good life into an evil one, because they are opposites, and conversion into what is opposite is extinction. And, being opposites, a good life is called Life, and an evil one Death. This is why religion is of life, and why its life is to do what is good. (That after death a man is such as had been his life in this world may be seen in the work on Heaven and Hell, n. 470-484).
