In Ephesians 4:11, Paul admonishes us to have no fellowship with the unfruitful works of darkness, but by bearing the fruit of light, expose them. This is what Jesus commands of His disciples in Matthew 5:13-16. We are the salt of the earth and the light of the world. The upshot of both metaphors is distinctiveness from the world. We are to be “salty” and “let our light shine,” not by tirades and verbal condemnations but by the way we live.
