I am sure you know well this prayer made into a hymn as well:
Lord, make me an instrument of Thy peace;
Where there is hatred, let me sow love;
Where there is injury, pardon;
Where there is error, truth;
Where there is doubt, faith;
Where there is despair, hope;
Where there is darkness, light;
And 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 in giving that we receive;
It is in pardoning that we are pardoned;
And it is in dying that we are born to eternal life.
