Why is pride so dangerous? What about pride undermines the gospel and leads people into self-deception and deceit? In this sermon on Romans 11:18–22 titled “Pride,” Dr. Martyn Lloyd-Jones preaches on the need to learn God’s word so as to fight against pride. Pride undermines the gospel because it makes people focus on themselves and their own works, justifying themselves. According to Dr. Lloyd-Jones, the great sin of many of the Jewish people who wanted to return to the law was the sin of pride. They sought to find salvation in their own identity and works but this is wholly opposed to the message of Jesus. Jesus Christ tells that one must forsake any chance of saving themselves. He tells that no works can makes one right before God. Pride makes the person look at what they do for their worth; Jesus makes them look to Him to find worth. Paul warns the church of his day about the danger of falling away from the gospel and looking to works to justify oneself. This is still a temptation for many Christians and for this reason, believers must always flee from self-righteousness and look to Jesus Christ and what He has done as Jesus alone saves.
