Seeing More and More of My Own Insufficiency

An excerpt of a letter from William Carey to his father, which left me saying, "I can relate!": 

I see more and more of my own insufficiency for the great work I am called to. The truths of God are amazingly profound, the souls of men infinitely precious, my own ignorance very great. . . .
