Some may respond with reason only is the absence of light. In a very widespread in yutobe video where a young argues with his teacher the arguments that this presents regarding the existence of God, there are expressions such as "if the evil exists and is not seen and touch it, then there is God, whom you can neither see nor touch", "the darkness exists only in the absence of light".
For centuries we have heard that God is guilty of the wickedness of the world, which sends it as a punishment for our bad behavior; but do you really?, in some verses that I have been able to read the Bible only describes a God of love, gracious, merciful and peaceful with his creation, and I am not referring only to the humanity, if not all of its creation, "a light invaluable for the earth and its inhabitants".

When we speak of darkness, we are talking about then the one who rebelled against their Creator letting the desire will prosper in the darkness of his heart, he got caught by the darkness of the envy and his dwelling place is in the deepest and darkest of the earth, where he was sent by God to be banished from the heavens, from there multiplies and increases the evil to all creation, to make us believe that all this evil that affects us; when he is going teetering between living beings in search of our weaknesses, fears and doubts to immerse ourselves in the deepest darkness.
"God radiates his light with words, example and truth"
Happy Day!
