I need a Christian girl much more than alcohol...
No Christian girl needs you. She's best staying as far away from someone with your attitude as possible.
Yet you think only of yourself, and what you think you need.
And no, you don't need to be perfect before you start looking.
I have a good friend whom I met while he was in prison, so his life wasn't exactly in order (nor was mine) when we met. But he was very different from the start. Even in prison, he had a job, he was always working and taking classes, and most importantly, he cared about the well-being of those around him.
Even though it was only a friendship, it's one that's now spanned almost 20 years. I went to visit him regularly at the prison when I was in the area for 10 years. He's been out for a while, and is doing fantastic, because he was working on meeting his goals from the very start.
Maybe he would have said he needed a Christian girl, too. And maybe God heard his prayer, and agreed with him.
But the vast difference between you and him was that even in his situation, he was concerned about what he could give and how he could help other people.
