The National Day of Prayer is a vital part of our American heritage. Since the first call to prayer in 1775, when the Continental Congress asked the colonies to pray for wisdom in forming a nation, the call to prayer has continued through our history, including President Lincoln’s proclamation of a day of “humiliation, fasting, and prayer” in 1863.
