This used to be one of the favorite prayers of my granddad:
Lord, make me an instrument of thy peace
Where there is hatred, let me sow love,
Where there is injury, pardon,
Where there is doubt, faith,
Where there is despair, hope,
Where there is darkness, light,
Where there is sadness, joy.
O Divine Master, grant that I may not so much seek
To be consoled as to console,
To be understood as to understand,
To be loved as to love;
For it is i giving that we receive;
It is in pardoning that we are pardoned;
It is in dying to self that we are born to eternal life
