A Prayer in the Wake of the Asian Tsunami Disaster – December 2004

Ruler of Creation, Master of the world:
Have mercy on all those who are suffering from the raging waters and the storming waves.
Have compassion on Your creatures – Look, O Lord, and see their distress;
Listen, God, and hear their cries.
Strengthen the hands of those who would bring relief, comfort the mourners,
Heal, please, the wounded.
Grant us wisdom and discernment to know our obligations,
and open our hearts so that we may extend our hands to the devastated.
Bless us so that we may walk in Your ways,
"compassionate ones, children of compassionate ones."
Grant us the will and the wisdom to prevent further disaster and death;
Prevent plague from descending upon Your earth, and fulfill Your words,
"Never again shall there be another flood to destroy the earth."
Amen. So may it be your will.
