I put the exact phrase "God is the LORD" in my Bible software program and there were 3 scriptures:
Ps 33:12 Blessed is the nation whose God is the LORD; and the people whom he hath chosen for his own inheritance.
Ps 118:27 God is the LORD, which hath shewed us light: bind the sacrifice with cords, even unto the horns of the altar.
Ps 144:15 Happy is that people, that is in such a case: yea, happy is that people, whose God is the LORD.
Here when I saw the first verse the one that came to my mind, I had forgotten the last part of it. When I read it "and the people whom he hath chosen for his own inheritance", I was like wow I never thought about us being an inheritance of God's. It was almost if the nation chose Almighty God which we the USA and states did, that God would claim us as his inheritance.
I hope you are searching scriptures with any words you hear that pop into your mind. It is great to see what the Lord has to say about things.
