It is reported that Mrs. Eddy constantly kept on her desk a hymn book open to John Henry Newman’s “Lead, Kindly Light.” Also, as she observed the “garish day” of pride and creeping materialism affecting the Boston church (especially the Board of Directors), she recommended that this hymn be sung often.
There are hundreds of testimonials bearing witness to the protective and transformative power of this prayer-hymn, how it has lifted so many up and out of seemingly impossible circumstances.
In keeping with the magnificent SH 299:7-17 passage quoted above, is the 3rd verse:

So long thy pow’r hath blest me, sure it still
Will lead me on
O’er moor and fen, o’er crag and torrent, till
The night is gone.
And with the morn those angel faces smile,
Which I have loved long since, and lost awhile!

“The morn” signifies the dawning of understanding, awakening to angel thoughts that come to anyone who responds to temptation properly, just as Jesus overcame the devil in the wilderness, and afterward, according to fixed principle, as day follows night, found himself in the company of angels.
