The justifications I received when asking others could be summarized (or categorized) as follows. This is non-exhaustive, so there may be other classifications that haven’t beem mentioned here.
I had a personal experience/revelation that let me know God exists
That’s fine for them. But I’ve not had that personal experience so it is left as hearsay for me.
Well I don’t really know, but I follow Christianity just in case. A Pascal’s wager variant (ex: I want to make sure I don’t burn in hell if it exists)
Doesn’t seem to be genuine conviction.
Tradition : your ancestors or other great people of the past were Christians
Imitation of previous generations doesn’t tell me of the truth value of Christian propositions.
I would become an outcast of my community/family if I were not a Christian
That can be a motivation to continue to behave as though one is a Christian (in some communities being an apostate makes one worthy of a social excommunication). Personal experience has shown me that people can be rather hostile once they find out you are not part of their in-group. Interesting from a sociology stand point. But this once again says nothing about the truth value of Christian propositions.
Some “logical” proof
None of the proofs that I’ve come across have been convincing to me. At best they are hypothetical projects dependent on some set of other untestable conditions being true.
Variants of arguments from ignorance: “You don’t there’s not a God.”/“How can you prove there is no God”/"If you don’t have an explanation you can’t say it’s not God"
I think that many don’t distinguish between someone not having knowledge that a certain proposition is true and some one declaring that a proposition is untrue.
Formal fallacies aside, Here are two propositions for which I cannot assign a truth value:
- There is life outside our solar system.
- There is no life outside our solar system.
I don’t defend either one of these propositions, but I don’t lend my support to any one that asserts either one of these. Similarly when a god-concept is interjected as an explanation for something I don’t declare that God had no involvement, but I don’t support assertions that God had involvement either. Neither proposition is convincing to me so I’m content to have an explanation without invoking a God until I find such a concept convincing.
