"Since our Nation's earliest days, prayer has given strength and comfort to Americans of all faiths. Our Founding Fathers relied on their faith to guide them as they built our democracy. Today, we continue to be inspired by God's blessings, mercy, and boundless love. As we observe this National Day of Prayer, we humbly acknowledge our reliance on the Almighty, express our gratitude for His blessings, and seek His guidance in our daily lives. Throughout our history, our Nation has turned to prayer for strength and guidance in times of challenge and uncertainty. ... Across our country, Americans turn daily to God in reverence. We ask Him to care for all those who suffer or feel helpless, knowing that God sees their needs and calls on us to meet them. As our first President wrote in 1790, 'May the father of all mercies scatter light and not darkness in our paths.' As we face the challenges of our times, God's purpose continues to guide us, and we continue to trust in the goodness of His plans." --President George W. Bush
Next, I bid your prayers for America, our President, your Governor and Congressmen, our service members and their leaders, the Church in America, and for peace and prosperity, families, communities, etc.
One might like to use a Litany of Prayers with special intention for America - pausing for the different verses and thinking of those things in your life that you wish to hold up in prayer. See it here http://www.orderofcenturions.org/documents/litany.html
"God shed His grace on thee."
