A prayer on the occasion of a disaster, from General Convention 2009
Written on January 16th, 2010
Compassionate God, whose Son Jesus wept at the grave of his friend Lazarus: Draw near to us in this time of sorrow and anguish, comfort those who mourn, strengthen those who are weary, encourage those in despair, and lead us all to fullness of life; through the same Jesus Christ, our Savior and Redeemer, who lives and reigns with you, in the unity of the Holy Spirit, God for ever and ever. Amen
