A nation provides every necessary means of support for its embassy and ambassador in a foreign land. Read Ephesians 3:20 and consider how much more powerfully and completely God provides for us while we live in this world: “Now to him who is able to do immeasurably more than all we ask or imagine, according to his power that is at work within us . . .”
We came to be ambassadors by God’s redemptive work, regenerating our souls in the image of Christ and powering that soul by His Word and Spirit, thus our citizenship by birth is in the kingdom of God/Heaven. Our lives are safe in the mighty fortress of God’s promises, but we are also protected as we freely move about in a land that is foreign and hostile to us—we have God’s version of diplomatic immunity.
God has given us the authority and responsibility to extend to others His Words and promises that have the power to rescue our fellow citizens when this foreign land threatens (Matthew 8, John 8) and to make the very foreigners around us citizens of His kingdom (from the calling of Matthew and Zacchaeus to the conversion of Paul!).
It is a powerful thing to have a regenerate soul as the essence of our person, regenerated in the image of Christ, and thus invulnerable as we live out God’s purpose for us in this world. Honest about our dependence of God, we remain conscious and alert to God’s support for us so that we might reach out in support of others.
