Is God big enough?

I heard a sermon one of my friends preached, and he was talking about the things we used to believe.  One of them was, that God was bigger than sin.

There was a lot more to that than just that, he said it more eloquently than I'm writing, and I'm representing him poorly.  But it did make me think.  

Do I really believe that God is big enough?  Bigger than my backache?  Bigger than my financial woes?  Bigger than my worries?  Those bigs seem so small.  What my friend was talking about was much bigger than these; like. . .

Is God bigger than sin. . .really?  I guess there was a day that people in the church believed that.  I'm wondering if we still do; cause if not, then sin wins.

What kind of a God is my God if sin wins?
