No, faith means you have confidence in something. ;-) For instance, I have faith that my car will get me safely to town, because it has already done so on hundreds of previous occasions. No one can guarantee that it will do so next time, but I have faith that it will.

No one thinks that God is physical. No one thinks that one's dreams for the future are physical either. No evidence can be provided for something that is not physical. But one's dreams for the future can serve as a very real motivator that can have real and tangible effects on the progress of one's life. Shall we, therefore, object to people having dreams for the future merely on the basis that no evidence can be provided to prove that those dreams exist?

If a human being's concept of "God" proves useful or comforting to him in some way, what business does anyone else have disparaging it on the basis that there is "no evidence" to support it? Why should there be any evidence for something which is, by definition, NOT physical?
