2 Corinthians 5:17-20
Though they live in a foreign nation, ambassadors take no part of their host nation's political or military institutions, yet the ambassador is expected to adhere to the laws of the foreign land. An American ambassador to China knows well that his host government is seriously opposed to his own. He does not serve the Chinese government, enter into its politics, try to eradicate the evils of its system, vote in its elections, join its army, or advocate for its causes. Yet he subjects himself to Chinese laws that concern him while there, endeavoring to behave in a way that will best represent the interests of the U.S. government.
In the same way, Christian's are ambassadors of the Kingdom of God. We are called to become part of a totally different society, and while living in this world, we must represent God and abide by His laws and standards, which supersede those of men when they conflict. Like the worldly ambassador, a Christian should not involve himself in the affairs of an opposing government but must abide by its rules as best he can. He must live as a citizen of heaven and an ambassador for Jesus Christ first and foremost.
