Though afflicted, tempest-toss-d,
Comfortless a while thou art,
Do not think thou canst be lost,
Thou are graven on my heart:
All thy wastes I will repair,
Thou shalt be rebuilt anew;
And in thee it shall appear
What a God of love can do.
-- John Newton, To the Afflicted, Tossed with Tempests, and Not Comforted
