In this sermon on Isaiah 5:20 titled “Moral Perversion,” Dr. Martyn Lloyd-Jones talks about how today’s society is particularly contaminated with perverse sin. He describes how society is not merely indulging in evil but also calling it good; for example, he describes how society looks down on the value of the family and encourages the exploration of sexuality before, during, and after marriage. He describes how this is the common path of sin. Once someone is fed with “common” sin they are no longer satisfied with it but give themselves over to a more “uncommon” or “perverse” sin. Take the example of a drunk who has their fill of alcohol but cannot attain the same experience they once had. They will very likely seek after drugs which give more of a high than alcohol. The same is true of theft, sexual immorality, and any other sin that entangles a person. Moreover, Dr. Lloyd-Jones describes how increased sin and perversion is always met with the wrath and justice of God. Dr. Lloyd-Jones powerfully concludes that perverse hearts need rebirth, that they need new desires and new hearts. This change can only be done by God, through Christ, and in the working of the Spirit.
