I believe that the starting point of faith is some doubt, not bein' so full of yourself and so confident that you are right and that God speaks only to us and doesn't speak to others, that God only cares about us and doesn't care about others.
I know that there are those who disagree with the overwhelming scientific evidence on climate change.
