Could we with ink the ocean fill,
  And were the skies of parchment made;
Were every stalk on earth a quill,
  And every man a scribe by trade;
To write the love of God above
  Would drain the ocean dry;
Nor could the scroll contain the whole,
  Though stretched from sky to sky.

"The Love of God"
This is the last stanza of the old hymn. It was said to be written on the wall of an asylum. But the author is unknown.
