A lot of people in this world does not accept the doctrines of Jesus Christ. A whole lot of people are walking in darkness. They have turned they face away from God and face the darkness. So, many people are living their lives without considering God. They refuse everything that has to do with God.
The true religion of God has been rejected by many. They make their own gods and serve them. Imagine people carving objects and different kinds of creatures with wood and making them God. These men make their own gods. They choose what they want to worship. They refuse to worship the true God.
When we turn our back to God, we will face the darkness. The darkness is were evil forces recide. The darkness can only lead us to evil. Because the world has rejected God and turned their back to Him, they are facing the darkness. It is the darkness that we follow that brings much evil upon us.
To be free from the evil in this world, we must return back to God. We must set our face on God to do His will. We must accept His ways. We must obey His commandments. Only when we return to God that we can be free from the evil that is tormenting this world.
