Ephesians 5:11-14

Do not participate in the worthless and unproductive deeds of darkness, but instead expose them [by exemplifying personal integrity, moral courage, and godly character]; for it is disgraceful even to mention the things that such people practice in secret. But all things become visible when they are exposed by the light [of God’s precepts], for it is light that makes everything visible. For this reason He says, “Awake, sleeper, And arise from the dead, And Christ will shine [as dawn] upon you and give you light.” [Is 26:19; 51:17; 52:1; 60:1, 2]
