I like this quote from Alexis De Tocqueville about American greatness:

"I sought for the key to the greatness of America in her harbors; in

her fertile fields and boundless forests; in her rich mines and vast

world commerce; in her public school system and institutions of

learning. I sought for it in her democratic Congress and in her

matchless Constitution. Not until I went into the churches of

America and heard her pulpits aflame with righteousness did I

understand the secret of her genius and power. America is great

because America is good, and if America ever ceases to be good,

America ceases to be great." ~ Alexis de Tocqueville.

Then you have to remember that nothing is good apart from God.

"And Jesus said to him, “Why do you call Me good? No one is good except God alone." Luke 18:19
