But to-night I wish to speak on just one thing that Paul said in that sermon, and these are the words: "God commandeth all men everywhere to repent." When we are commanded to do something, we like to know what it is we are commanded to do. Now I will tell you. It is to repent. But you may say, "I do not exactly know what that means." I will now tell you about all I know of the meaning of the words repent and repentance. The Lord Jesus knew exactly what these words mean, and I will give you his definition. He said to the Jews: "The men of Nineveh repented at the preaching of Jonah." Now let us turn to the book of Jonah in the Old Testament and see what the men of Nineveh did at the preaching of Jonah, and we will then understand what the Lord meant when he said they _repented_. You must know what Jonah's sermon was. It was so plain that all could understand it, and so short that all could remember it, This is the sermon: "Yet forty days and Nineveh shall be destroyed." The city had more than a hundred and twenty thousand people in it; and it took Jonah three days to go from one end to the other with his message of destruction; but at the end of the first day "the people of Nineveh believed God; and when the word came unto the king of Nineveh he arose from his throne, and laid his robe from him, and put on sackcloth, and sat in ashes and said: Let man and beast be covered with sackcloth, and cry mightily to God; yea, let them turn, every one from his evil way. And God saw their works, that they turned from their evil way." Now, notice, when God commands all men everywhere to repent, he means for them to do what the Ninevites did, but in a more spiritually enlightened way. They believed God. This is the first step in repentance, as this same apostle says: "He that would come unto God must believe that he is, and that he is a rewarder of them that diligently seek him." The Ninevites had no written word as we have, that gives us intelligent knowledge of God as he is revealed in the face of his Son Jesus Christ. All they knew of him was from tradition, and what they could see of him in his works. But they believed God, and gave proof of it by turning from their evil way. Now, friends, this is just what God commands all men to do. This is what he commands every impenitent man and woman in this house to do to-night.
