What has always been the most hideous of mankind's sins throughout history?
Scripture teaches that sexual immorality is the most hideous of mankind's sins throughout history. The works of the flesh are manifest; they cannot be hidden or doubted. The list begins with sexual sins and adultery, showing that this area is primary among the flesh's manifestations.
Les teaches that the works of the flesh of old Adam are manifest—there is no hiding or doubting them, like looking into a microscope and seeing everything exposed by a bright light from below. He notes that the list starts with sexual sins and adultery, then asks what has always been the most hideous of mankind's sins throughout history, answering: sexual immorality. This comes in the context of Galatians 2, verse 19, and the truth that once a person enters the Spirit-led life, they are not under Law but under Grace, regardless of their season of life.
