There is a wonderful prayer I'd like to share on kindness and I hope it is in keeping with the topic's theme:
"Lord, help me to live from day to day
in such a self-forgetful way
that even when I kneel to pray
my prayers shall be for others.
Help me in all the work I do
to be ever sincere and true
and know that all I do for You
must needs be done for others.
And when my work on earth is done
and my new work in heaven begun
may I forget the crown I've won
while thinking still of others.
Others, Lord, yes, others
let this my motto be.
Help me to live for others
that I may live for Thee."
