Dwight L. Moody told this story: "A minister was one day moving his library upstairs. As he was going up with a load of books, his little boy came in, and was very anxious to help his father. So his father just told him to go and get an armful, and bring them upstairs. When the father came back, he met the little fellow about half-way up, tugging away at the biggest book in the library. He couldn't manage to carry it up. It was too big. So he sat down and cried.
"His father found him, and just took him in his arms, book and all, and carried him upstairs. So Christ will carry you and all your burdens, if you will but let Him."
