But I mean faith is trust on evidences and Christianity is not far from this definition.
First if God doesn't exist, objective moral values do not exist. It is only pure subjective.In a deep sense there is no real right and wrong. Right and wrong are the same.But heres the catch.Why we tend to see things really wrong and really right if there is no objectivity of it?
honestly, believing that there is a God is not blind faith or just I believe it without any convincing reasons. Like the great thinkers of the old-Anselm, Augustine,Aquinas, Leibniz etc, it's not just blind faith that I believe in God aside from my personal experience of Him. Obviously like them, I critically think it.Anselm for example invented the ontological argument which is still hotly debated today.
Watch the debate between William lane Craig and Kevin Scharp-" Is there evidence for God in youtube and it is explaiined well by WLC.
