John Rutter Music combined with Sacred texts = peace

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;
and all for thy mercy's sake.
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."

-from Saint Francis of Assisi, 1181-1226
