1 Peter 2:11-12 

God has formed us into a new nation, and sent us into this world as the ambassadors of His kingdom. As His ambassadors we must not live by the same sinful desires that this world lives by, so that outsiders can see that Christ’s kingdom is different. We must also let our lives be continually marked by good deeds, so that people can learn of the Glory and Goodness of God and be drawn to become citizens of God's country.
