This is the message which we have heard from him and announce to you, that God is light, and in him is no darkness at all.

 (v) The darkness stands for the immorality of the Christless life. It is Paul's appeal to men that they should cast off the works of darkness ( Romans 13:12). Men, because their deeds were evil, loved the darkness rather than the light ( John 3:19). The darkness stands for the way that the Christless life is filled with things which seek the shadows because they cannot stand the light.
