How does darkness relate to hatred towards others?

In 1 John 2:11, John explains that 'he that hateth his brother is in darkness, and walketh in darkness.' This stark contrast portrays that hatred is a manifestation of spiritual blindness and separation from the light of God. The idea of walking in darkness is synonymous with a life devoid of the guiding principles of Scripture and the transformative love of Christ. For those holding to sovereign grace, such a state serves as a warning about the dangers of false assurance and the need for true regeneration through the Holy Spirit, leading to a genuine love for others.
