Missionaries who think they're going overseas to do a great work for Jesus amuse me. First, we merely participate in the work God is already doing. This is well explained in the book Experiencing God, by Henry Blackaby. Of course, all our friends at home will tell us what a great and wonderful thing we're doing. Then WHAM! We come face-to-face overseas with all our inadequacies and weaknesses. We realize how much we're actually going to have to depend on God to see something accomplished. Many missionaries, when confronted with the reality of living in a foreign culture and the time needed to influence people, simply become discouraged, turn around, and come home. Only when we realize our total dependence on God, wait on him, and work with him do we finally see some beautiful fruit.
