I had gotten this from the same sight that I first listened to the sermon itself just now. It had struck me to my heart. And is a good reminder that God has used so many people in the past, and many more now and in the future to teach his will to the masses. And that all we need to do is to open our eyes to see it.
The following description and audiobook/sermon are from learnoutloud.
“Written in 1880 by Scottish evangelist Henry Drummond, The Greatest Thing in the World draws its message from the Apostle Paul’s argument that love is man’s true path to God. Using a key text from 1st Corinthians, Drummond argues that while there are many virtuous emotions we all must practice cultivating in order to live a fuller life, none is more paramount than a loving outlook. With an urgent passion that bespeaks the era in which he lived, Drummond testifies that if we only take a little more time each day to operate from a basis of loving kindness, others will notice and be attracted to our living example.
