“But anyone who hates a brother or sister is in the darkness and walks around in the darkness. They do not know where they are going, because the darkness has blinded them.”
1 John 2:11

The Greek word here for hate is miseo, meaning to hate, pursue with hatred, detest, especially to persecute. A form of persecution against Christianity is a lack of love amongst believers in a fellowship. Those that demonstrate this behavior live in darkness, unsure and insecure, because of their choices, their path is not made clear to them.
