D. L. Moody wrote the following words next to Isaiah 6:8 in his Bible: “I am only one, but I am one. I cannot do everything, but I can do something. What I can do, I ought to do, and what I ought to do, by the grace of God I will do.”
Isaiah 6:8: “Also I heard the voice of the Lord, saying, Whom shall I send, and who will go for us? Then said I, Here am I; send me.”
