I live in sin
Folks, I'm not a lesbian (unless you count a lesbian trapped in a man's body), but I live in sin. I hate to break it to you, but so do you.
Your sin isn't greater than mine, and vice-versa. If you buy Christianity, you must believe that we're all sinners. I'm from the school that sin is sin, because sin separates us from God, whether that be telling a little white lie to murdering someone. So please don't tell me that so-and-so is "living in sin" and ask me to pray for them without asking for prayer for yourself.
So pray for me. I am a sinner and I live in sin.
