Absolutely. I am ready to do whatever God calls upon me to do. I live for His will, not my own.
Brave people aren't the ones who do things they're not afraid to me. Brave people are those who have the courage to do what's asked of them or needed of them even though they don't think they're good enough, don't know how, or are scared.
When I went on my first mission trip in 2008, I went to Kenya and I remember saying, "God, I'm willing to serve, but please don't make me serve with children." And you know what? During our week there, we spent time with more than 300 children hosting a Vacation Bible Study for them. It worked out just fine, as God knew it would. Was it what I would have chosen for myself? No. But I did what God asked me to do.
