In regards to Buddhism, they try to justify rebirth, even though there is no such thing as a soul. I remember reading a poster use this point.
*There is no unchanging eternal core, no soul. Greatly simplifying things, Christianity sees the world as essentially unchanging with a veneer of apparent change laid over it. Buddhism sees the reverse; the world is essentially changing with a veneer of apparent stasis laid over it…if your light a candle with another candle, is it the same flame, or not the same flame?
My question is, as Christians, how can we prove that an unchanging universe is the correct outlook instead of an always-changing one?
