One reason I have for having doubt about the "christian" faith is that so many 'christians' are like my old fundamentalist grandma whose beliefs were thus: when someone sins, you forgive them but you love them a little less to remind them that they're a sinner. That goes against all the so-called 'christian' teachings. There are a few people on this site who practice christianity the way my old grandma practiced it.
That sh!t turns me off to christianity faster than anything. I am currently doing the AA steps and am now on step seven "humbly asked Him to remove our shortcomings" but am having a hard time with it cause I'm not even sure He exists, much less cares about me. It's a constant battle in my head: wanting to believe in a loving God and doubting that He cares about me at all.
Reminds me of a prayer I heard long ago: "Oh God, if there is a God, save my soul, if I have a soul". That pretty much sums it up for me...
