And can it be that even on our darkest days when we face our most difficult people God is giving us opportunity to show mercy? Maybe He leads us through the valley of the shadow so that we can learn to forgive even there. A bit further on and on sunnier days we may discover how merciful and forgiving He has been to us when we were most dark and difficult with others.

Blessed are the merciful for they shall receive mercy  Matthew 5:7
