[as part of his guide to the t4c mob, "perfectly pure", advising them how to resist sexual sin]

Another thing to consider is your music. While it is true that you can commit a sin while listening to Handel’s Messiah, it is not likely that the Halleluiah Chorus is going to stimulate your flesh into such a way as to cause you to sin. There are, however, certain types of music that will do this. Even music that claims to be Christian can stimulate your flesh and cause you to sin. Music cannot be separated from the flesh. It is my opinion that before he fell, Satan was in charge of the music in Heaven. Even if this were not true, Satan uses music as a very powerful influence in our lives.
