Concerned about someone's faith

I was concerned today about someone's faith. This person is close to me and has made decisions that I know are not going to draw him closer to God. So, I called my friend Connie, and asked her what to do. She listened to me and then said, "Marsha, you know that verse, 'work out your own salvation with fear and trembling'?" I said, "Yes". She said, "Well, you can't work out his, just yours."

So apparently the lesson is, it's only my salvation I'm to work on figuring out - not someone else's. How freeing this is to my normally codependant ways.
