Even stars, apparently immutable, cannot give one a hope of immortality, because even if you have a constellation named after you, the names change constantly. But! Christianity provides far better hopes of immortality than anything in this world. Epitaphs and tombs get destroyed, but Moses, whose tomb is unknown, lives perpetually with God. The only true death will happen to the condemned at the Last Judgement. Truly pious people consider this world as meaningless as the primordial chaos before it, because it is the eternal life after death that truly matters. So, summing up, it is only pagans who had to care about their funeral monuments and perpetuating their name, but for true Christians these things don’t matter and death is something they can really look forward to.
