Treasures of Wisdom is a devotional booklet containing writings of Martha Wing Robinson. The booklet was compiled by Mr. and Mrs. Gordon P. Gardiner.
Mr. Gardiner wrote a biography on Mrs. Robinson's life entitled "Radiant Glory" which you can read online here: https://sites.google.com/site/radiantglory/radiantglory-contents
(Just started reading this booklet recently and it has been such a blessing. Will try to post each day's entry in hope that it might be a blessing to those on Sermon Index too.)
