I refuse to confuse the kingdom of God with human politics. I don't for one minute believe that God ONLY wants to bless America. ALL THE NATIONS OF THE EARTH ARE BLESSED IN CHRIST! I have heard verses such as this one misused all my life to insist that America has some special destiny given by God.
The reality is that God wants all people everywhere to repent. Righteousness could exalt China, or North Korea, or Iran, or Venezuela. God wants to bless Cuba! God wants to see Palestinians and Israelis alike live in His righteousness. The goal for all of this is the glory of God in obedience to the gospel! Politics and national boundaries are hindrances to this.
No flags wave over God's wisdom. Not nation can claim exclusivity. God rules all the nations. No one ethnic group or national leader can claim to be the sole recipient of God's blessing. Righteousness exalts God an any people who will trust Him. Sin is the universal enemy of that worldwide vision for humanity.
