Here is a beautiful prayer for the world from Rabbi Harold Kushner.
Prayer for the World
Let the rain come and wash away
the ancient grudges, the bitter hatreds
held and nurtured over generations.
Let the rain wash away the memory
of the hurt, the neglect.
Then let the sun come out and
fill the sky with rainbows.
Let the warmth of the sun heal us
wherever we are broken.
Let it burn away the fog so that
we can see each other clearly,
so that we can see beyond labels,
beyond accents, gender or skin color.
Let the warmth and brightness
of the sun melt our selfishness,
so that we can share the joys and
feel the sorrows of our neighbors.
And let the light of the sun
be so strong that we will see all
people as our neighbors.
Let the earth, nourished by rain,
bring forth flowers
to surround us with beauty.
And let the mountains teach our hearts
to reach upward to heaven.
