We should be tolerant of other's beliefs. I agree the topic of religion is inappropiate in this forum, but I hope I can get away with it in this thread.
The signoff is indeed part of someone's personality. If I signed off my posts with 'good luck', I doubt anyone would be offended even if they didn't believe in luck. The same should hold true with 'God bless'.
Ken's response to Stephen prompted me to post. The same subject was presented to me by a fellow engineer. He could't understand how I could have so much knowledge about science, and at the same believe in a supreme being as the origin of life.
Ken, thank you for your well written post. You hit the nail on the head when you said
The point is our frames of reference are different
The frame of reference for a Believer is more than just faith. I had a physical experience when I became 'Born Again'. For your 10 volt wire analogy, I see 0 volts on the meter the same as you, but when I touched the wires I got a shock.
The frame of reference can be clearly defined, and BOTH of them are based on faith. You believe in what you see, hear, and feel. So do I.
The difference is that I have felt God, and therefore declare his existance as an absolute. To convice me otherwise, you need to explain the cause of my perpetual delusional state. Many think Christians are just crazy. If God doesn't exist, then that can be the only explaination!
Ken, allow me to end this with a bit of kidding. Are you aware of the origin of "D--n it"? You are praying to God to condem the thing to Hades.
