"Our message is simple. There is a clear covenant implied in our Declaration of Independence—a covenant between God, the People, and the Government. When we, the People, turn our hearts to God more than to our government or to ourselves, His Providence increases our personal wisdom and decreases our government dependence. We are individually and collectively freed."

There is only one nation that has a covenant with God and that's the nation Israel. America is not Israel. Dr. Tommy Ice, in his critique of Messianic Rabbi Jonathan Cahn's book The Harbinger answering the question, "Is America A Covenant Nation?" writes:
If Cahn somehow thinks that America is a covenant nation with God because our founders primarily during the Colonial Period were devout Christians, which they were, that does not mean that God recognizes such nations as being in a covenantal relationship like Israel. Things like the Mayflower Compact were not made with God but horizontally between the Pilgrims to honor God and do other things. No doubt, the 167 years of Colonial America provided perhaps the greatest Christian basis for any nation in history, but somehow making our country a "covenant nation" like Israel simply could not and did not happen.
Dr. Tommy Ice further writes:
The Lord declares, "but I have chosen Jerusalem that My name might be there and I have chosen David to be over My people Israel" [2 Chronicles](6:6). You don't volunteer to be God's chosen people, He must choose you and He has only chosen the nation of Israel!
