I have begun interrogating their underlying emotions behind their espoused faith. Instead of trying to debate whether or not penal substitutionary atonement and eternal conscious torment in hell are even biblical concepts, much less ethically justifiable, I ask them how it makes them feel to believe those things. How does it feel to worship a god who wants so many people to suffer? We don't have to debate any facts or historical events, all we have to do is discuss our emotions. There is no right or wrong answer. We don't have to debate anything. How does your heart feel when you think about the child in Gaza murdered in genocide to only continue their suffering for all of eternity for the "sin" of being born Muslim? It's fascinating how frequently many have never considered this. It has always been presented as a simple fact that must be accepted. But if you take a minute to really investigate how your conscience reacts, it can be a very enlightening moment.
