"So in our modern evangelism we cast our pearls (the costliest pearl being the gospel) before swine. People cannot see the beauty of the pearl, because they have no conception of the filth of the pigsty. No man has ever appreciated the gospel until the law has first revealed him to himself. It is only against the inky blackness of the night sky that the stars being to appear, and it is only against the dark background of sin and judgement that the gospel shines forth."

John Stott, Galatians
