I need a Bible verse concerning short-term mission work..?

Hello! This summer, I will be taking a 10-day mission trip to Kiev, Ukraine. I am sending out support letters this week, asking people to pray for our team and to prayerfully consider contributing financially. I have a good letter written out, but I would like to include a Bible verse at the bottom. The Bible verse should probably have something to do with missions or heeding the call of the Lord. I know the Great Commision, but I am trying to think a little more creatively! Any help is appreciated. Thanks!
