As muddy water is best cleared by leaving it alone, it could be argued that those who sit quietly and do nothing are making one of the best possible contributions to a world in turmoil.

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!
