Lord, make me an instrument of your peace.
Where there is hatred, let me bring love. Where there is offence, let me bring pardon. Where there is discord, let me bring union. Where there is error, let me bring truth. Where there is doubt, let me bring faith. Where there is despair, let me bring hope. Where there is darkness, let me bring your light. Where there is sadness, let me bring joy.
O Lord, 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 self-forgetting that we may find, it is in pardoning that we are pardoned.
It is in dying that we are awakened to eternal life.
Simple Prayer for Peace from 1912 (aka Peace Prayer of St Francis, or Make me an instrument of Your Peace)
