Full Idea
Religion is capable of 'eschatological verification', by reaching evidence at the end of life, even though falsification of its claims is never found in this life; a prediction of coming to a Celestial City must await the end of the journey.
Gist of Idea
Belief in an afterlife may be unverifiable in this life, but it will be verifiable after death
