I had just heard a message on Jacob's wrestling match with God, and how God gave him a new name and a limp. His new name, Israel, means "he struggles with God." I was going through some difficult things at the time, and in a time of prayer afterward I asked God to give me a new name... whatever that means today.
A few days later, a friend and I were discussing how we deal with our relationships with women. I am by no means a Master of Communications With Females (as soon as you start to consider yourself one you crash and burn), but I find that I have some good things I can impart to my fellow men on the subject. After hearing about how I have dealt with some situations in the past, he was impressed with my ability to reason through these situations and handle myself confidently. I think my biggest advantage is that I know how to be friends with women.
"Courage. That's your new name. I'm gonna call you Courage," my friend said. My friend who hadn't been at the talk a few days before; besides, no one had heard my prayer. Except God.
I believe God is conscious of everything that happens in my life, and thus I don't believe that I should disregard things that seem like chance as meaningless. On the other hand, one shouldn't over-spiritualize things (like seeing Jesus's image in a piece of toast or having all green lights on the way to work and taking it as a sign to do something).
That said, I think God did the name thing intentionally. It doesn't indicate a paradigm shift in the direction of my life or anything on that scale, but it is something I treasure and am encouraged by.
