8. The reason why all religion has relation to life is, because every one after death is his own life. For every one's life remains the same as it had been in the world, and is not changed; as an evil life cannot be converted into a good life, nor a good life into an evil one because they are opposites, and conversion into an opposite is extinction; and thus, because they are opposites, a good life is called life, and an evil life is called death. Hence it is that religion has relation to life, and that the life [of religion] is to do good. That man after death is such as his life has been in the world, may be seen in the work on Heaven and Hell Nos. 470-484.
