What about other people's genuine experience of God?
Your "experience of God" is delusional, not real
Your relationship with God is just a psychological crutch!
How can you say you have found the truth if you haven't tried all the alternatives?
If Christianity is about relationship with God, why does He let bad things happen to his friends?
If Christianity is about a transforming relationship with God, why are Christians so bad?
If God is so loving and relational, why did He go ahead and create when he knew people would end up in hell?
Belief in God is dangerous
I used to believe, but I've given it all up
