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.
