Blessed is the nation whose God is the LORD, the people he has chosen for His personal inheritance. And there it is – not a promise or offer that by choosing the LORD any nation whatsoever can be blessed, but a statement that the nation God himself has chosen will be blessed.

2 Chronicles 7:14

God blesses nations who humbly seek Him. “…if my people, who are called by my name, will humble themselves and pray and seek my face and turn from their wicked ways, then will I hear from heaven and will forgive their sin and will heal their land.”
