This is the judgment: The light has come into the world, and people loved darkness rather than the light because their deeds were evil. For everyone who does evil hates the light and avoids it, so that his deeds may not be exposed. But anyone who lives by the truth comes to the light, so that his works may be shown to be accomplished by God.” (John 3:19-21)

This is the message we have heard from him and declare to you: God is light, and there is absolutely no darkness in him. If we say, “We have fellowship with him,” and yet we walk in darkness, we are lying and are not practicing the truth. If we walk in the light as he himself is in the light, we have fellowship with one another, and the blood of Jesus his Son cleanses us from all sin. (1 John 1:5-7)

For you were once darkness, but now you are light in the Lord. Walk as children of light — for the fruit of the light consists of all goodness, righteousness, and truth — testing what is pleasing to the Lord. Don’t participate in the fruitless works of darkness, but instead expose them. (Ephesians 5:8-11)
