God does not need us, but He chooses to use us in the fulfillment of His perfect plan and to share His love with the world around us. In 2 Corinthians 5:20 Paul says, We are therefore Christ’s  ambassadors, as though God were making his appeal through us. We implore you on Christ’s behalf: Be reconciled to God. Just as an ambassador in a foreign land represents the United States and it’s interests, so are we ambassadors of God in this fallen world. Where we belong and who we belong to does not change, but we live here as representatives of Christ.
