Name one thing in your life that you have faith in that has no evidence to back up your faith.
Again, you use faith as a belief in a physical thing. I have faith in the sanctity of human life. I have faith in and firmly believe that the family unit (without making a judgment who is necessarily in that unit) is the strongest entity we have to fight sin, hypocrisy and most evil.
This answer is assuming, of course, that you don't want to hear about the resurrection of Christ, or some other tenet of my religion.
