I remember a number of years ago I got cast down for a good many weeks. One Sunday in particular I had preached and there did not seem to be any result. On the Monday I was very much cast down. I was sitting in my study and was looking at myself, brooding over my want of success. A young man called upon me, who had a Bible class of 100 adults in the Sabbath-school which I conducted. As he came in I could see he was away upon the mountain top, while I was down in the valley. Said he to me, "What kind of a day did you have yesterday?" "Very poor; I had no success, and I feel quite cast down. How did you get on?" "Oh, grandly; I never had a better day." "What was your subject?" "I had the life and character of Noah. Did you ever preach on Noah? Did you ever study up his life?" "Well, no; I do not know as ever I made it a special study." I thought I knew pretty well all there was about him in the Bible; you know all that is told us about him is contained in a few verses. "If you never studied it before, you had better do it now. It will do you good. Noah was a wonderful character." When the young man went out I got my Bible and some other books, and read all I could find about Noah, I had not been reading long before the thought came stealing over me: Here was a man who toiled on for a hundred and twenty years and never had a single convert outside of his own family. Yet he did not get discouraged. I closed up my Bible; the cloud had gone; I started out and went to the noon prayer-meeting. I had not been there long when a man got up and said he had come from a little town in Illinois. On the day before he had admitted a hundred young converts to Church membership. As he was speaking I said to myself: "I wonder what Noah would have given if he could have heard that. He never had any such result as that to his labors." Then in a little while a man who sat right behind me stood up. His hand was on the seat, and I felt it shake; I could realise that the man was trembling. He said: "I wish you would pray for me; I would like to become a Christian." Thought I to myself: "wonder what Noah would have given if he had heard that. He never heard a single soul asking God for mercy, yet he did not get discouraged." I have never hung my harp on the willows since that day. Let us ask God to take away the clouds of fear and unbelief; let us get out of Doubting Castle; let us move forward courageously in the name of our God and expect to see results.
