Is the devil black or white?

This maybe sound like a strange question to you, since the devil is a spiritual being, therefore having no "skin color". Of course i'm not talking about the devil's "skin color" nor i'm saying that the black color means evil, i'm talking about satan's character, since he is described in the Bible as the "ruler of the darkness": Ephesians 6:12; a "murderer" and the "father of lies": John 8:44; the "adversary": 1 Peter 5:8; the "wicked one": Matthew 13:19. How many times you heard people (including christians) telling what's called "white lies" without any shame of doing it? Since the devil is the father of lies and he is evil, we must answer these questions: Is there a "good" or "white" lie? Is there a "good" sin? When satan transforms himself into an angel of light (2 Corinthians 11:14), does he become a "good" evil? Can light have communion with darkness (2 Corinthians 6:14)? Can we have sunshine and darkness simultaneously? Unfortunately, we have made so many concessions regarding to sin, that is very hard to fully speak the truth, "nothing but the truth". We've been living a double life, where we're trying to please God and satan at the same time, in the same sentence speaking truth and lying. If an episode like the lying of Ananias and Sapphira (Acts 5), happens in our churches and we "detect" (discern) it, it'll be considered "normal" or just another "white lie". In the early church, Ananias and Sapphira's "white lie" cost their lives. Today, it probably wouldn't cost anything, because of our lack of discernment, we wouldn't even know that they were lying, instead, we'd probably "praise" them for doing such a beautiful act of compassion. Our "modern" Christianity is way too casual, there's very little if any of what the Bible calls "Fear of God" in our midst. How much "blood" are we shedding in our fight against sin? Hebrews 12:4. Are we really striving against sin or just giving up easily? Does sinning makes us cry for forgiveness or have we numb our conscience by never confessing our sins? Are we in and of the world or are we in but not of the world? John 15:19.
