I love the note. I also tend to agree with it. Which is not to say that there is no proof, or that we shouldn't look for proof. But rather, faith, by definition, is the belief with the lack of proof (not the absence of proof but the transcendence of it through direct experience of God).

Hebrews 11:1 says "Now faith is confidence in what we hope for and assurance about what we do not see."

Regarding Point 1, Jesus said that proof will even not be enough. Speaking of that, I sometimes take a fatalistic position in that I wonder if there is anything I can do to change someone's mind. I have to remind myself that it is God who calls and I am merely the witness.

Read Luke 16:19-31. Verse 31: "He said to him, 'If they do not listen to Moses and the Prophets, they will not be convinced even if someone rises from the dead.'"

I love the piano analogy in Point 2. By the way, respect for Hill Street Blues theme!

Re Point 3, I believe pride is the primary reason - in many cases, all other reasons are a justification to allow us to continue to believe that we don't need God. Lack of proof or bad experiences are just a way of explaining or justifying our prideful position.

Of all the "reasons," guilt is the one with the most hope, since I believe that is a subconscious acknowledgment of a need for God.
