Jesus said it best--Healthy people don't need a doctor. 8^)
I had a fundamentalist girlfriend once, and I hung out with her crowd. They loved to 'witness' to me about the miracles God had performed in their lives. "I was a drug addict. I stole money from my parents/my spouse/my employer to buy drugs. I lost my friends, my family, my job, my home. God pulled me out of the gutter and I became a whole new person! I was BORN AGAIN!" I heard this story over and over, just with different details.
And I got to thinking, maybe this was why Christianity didn't work for ME. I'd never been a horrible person. Weak, maybe. Made some bad decisions (and paid for them). You name the sin, I've sinned it, but no worse than the average person.
Maybe that's what you need to be a Christian, to live a HORRIBLE life, a life of sin and debauchery, of sex, drugs and rock-n-roll. Then somehow you get a clue, you find a life, you rise out of the morass, and complacently believe God pulled you out. Because he loves you. Because you're special.
