Think carefully about believing something, even by faith. It always results in action. Believe it’s going to rain? Bring an umbrella. Believe a movie will be good? Go see it. Believe someone did a good job? Maybe give them a high five. Believe in God? I think at a minimum you’d want to know more. You will still be who you are, but your “lens” might be slightly different. So, do you really have faith in God?
I don’t think I can have faith, in that case. \ I can’t be who I am when you put it like that. \ Yes, I’m certain.
