I love how President Abraham Lincoln pointed out to Americans that our pride can cause our nation to suffer:
“We have been the recipients of the choicest bounties of heaven; we have been preserved these many years in peace and prosperity; we have grown in numbers, wealth, and power as no other nation has ever grown. But we have forgotten God. We have forgotten the gracious hand which preserved us in peace and multiplied and enriched and strengthened us, and we have vainly imagined, in the deceitfulness of our hearts, that all these blessings were produced by some superior wisdom and virtue of our own. Intoxicated with unbroken success, we have become too self-sufficient to feel the necessity of redeeming and preserving grace, too proud to pray to the God that made us.”
A. Lincoln, Proclamation of a day of National Humiliation, Fasting and Prayer, 1863.
