On the anniversary of September 11 the following prayer may be appropriate.
Almighty God, Lord of all peoples and nations on the earth,
whose power no one is able to resist.
Protect, save and deliver us, we humbly pray, from the hands of our enemies;
Halt their pride and self-righteousness,
Lessen their malice and anger,
Confound their plans and sow confusion among those who lead them;
Strengthen the will and wisdom of our national leaders: both civil and military,
That we, and all who represent us, being armed with your defense,
may be preserved evermore from all perils, to glorify you, the only giver of true victory,
Through the merits of your only Son, Jesus Christ our Lord, the Prince of Peace. Amen.
