There is much talk these days about self-confidence.  This message isn't so much about self-confidence as it is God-confidence.  God sometimes call us to serve in ways that seem impossible.  On the one hand our instincts are correct, sometimes these tasks are beyond us.  However, they are not beyond God and God does not call us to serve alone.  God goes with us.  Ultimately it is God at work in us and we ought to trust in God's ability to do so.  Trust in God and you will not only witness the power of God at work in the word, you will be a part of it.
