Check out this prayer from Beliefnet’s prayer library:

God of heaven and earth, God who carries our lives and the lives of our whole community in your hands, be with us in the peril of this day/night. Help us to release our anxieties and fears into those same caring hands, knowing in faith that your will for us is life and everlasting good. Send your holy angels to watch over us and guard us. May they spread their holy wings to give us shelter against the storm. For you alone, O God, are all good, all life, all love, and that love is for us; through Jesus Christ our Lord.
