In this sermon, visiting missionary Dwayne King draws upon a life of missionary service to affirm God's promises to the church in 2 Corinthians 5. While we may sometimes wonder what God is doing and why, we can rest with assurance that He is in control of our lives and ministry as His witnesses. God's sovereign purpose governs not only the events of the entire world, our also our personal efforts to share the gospel as ambassadors for Christ.
