Larry Osborne (pastor in CA) gave a good quote last week: "God likes to use the wrong people to do great things." Think about the 12 disciples...a tax collector, some fishermen, all kinds of men from different backgrounds...that many people would have written off. In our culture we look for the best-educated, most-experienced person for a job. But Jesus looked for men who had willing hearts and were teachable.
Think about this for you...No matter who you are or where you have been, God can use you...that just has to encourage you!
