If you want to mean the words more

James Keifer's brief online biography for former Archbishop of Canterbury William Temple (1881-1944) tells of an inspirational moment in a revival service:

In 1931, at the end of the Oxford Mission (what is known in many Protestant circles as a Revival Meeting), he led a congregation in the University Church, St Mary the Virgin, in the singing of the hymn, "When I Survey the Wondrous Cross." Just before the last stanza, he stopped them and asked them to read the words to themselves. "Now," he said, if you mean them with all your heart, sing them as loud as you can. If you don't mean them at all, keep silent. If you mean them even a little and want to mean them more, sing them very softly." The organ played, and two thousand voices whispered:

Were the whole realm of nature mine,
That were an offering far too small;
Love so amazing, so divine,
Demands my soul, my life, my all.

For many who participated, it was a never-forgotten experience.
