1 John 3:11-13 Sermon: The Love of God and the Hatred of Cain

John emphasizes that Christians are called to love one another, as this is a core message they have heard from the beginning and is central to following Christ. He contrasts love with the example of Cain, who acted in hatred and murdered his brother, showing that hatred is aligned with evil. John also warns believers that the world will hate them, but they should remain steadfast in love, following the example of Jesus, who laid down His life for others.
