We've taken our life's motto is actually from a quote by Pres. Spencer W. Kimball noted in "The Life and Ministry of Spencer W. Kimball", page xxxvi:
On November 5, 1985, after nearly 12 years serving as President of the Church, Spencer W. Kimball passed away.
At the time of his passing, President Kimball’s counselor President Gordon B. Hinckley declared: “It has been my great privilege and opportunity to work at President Kimball’s side in the harness of the work of the Lord. On one occasion I tried to slow him down a little, and he said,
‘Gordon, my life is like my shoes—to be worn out in service.’
He so lived. He so died. He has gone to the company of Him whose servant he was, even the Lord Jesus Christ, of whom he bore witness and testimony.”
We've paraphrased the Pres Kimball's quote to personalize it to us, so that it is written upon our hearts:
"Our life is like our shoes, to be worn out in the service of our God!"
