I came across this poem/prayer which I think is worth pondering...

Lord, we give you thanks for the gift of tears:

For tears of grief, redeeming our mourning from despair;

For tears of anger, awakening our thirst for justice;

For tears of laughter, celebrating our joy in living.

May the light of Christ shining through our tears

Become a rainbow of your promise,

Shedding colours of your love's bright presence

In your grieving, struggling, laughing world.
