In this sermon on Romans 11:18–22 titled “Vital Principles,” Dr. Martyn Lloyd-Jones urges listeners to always seek the truth and facts. Throughout history, people have gone astray because they did not seek the truth and history teaches lessons that are applicable for today. Scripture is the same way and can be looked to for truth. Dr. Lloyd-Jones outlines three points regarding truth. First, God’s people always have a tendency to fall away from the truth and this is seen throughout history and in Scripture. Second, the cause of this is because they forget the first and original principles. Every problem in this world is because people forget. Lastly, those who fall away are the ones who most persecute those who hold true to the principles. The Jews, specifically, are a people group who fell away and began to persecute those who believed the true gospel. Dr. Lloyd-Jones warns against those who do not actively pursue truth.
