1 John 3:11-15

The beautiful message you’ve heard right from the start is that we should walk in self-sacrificing love toward one another. We should not be like Cain, who yielded to the Evil One and brutally murdered his own brother, Abel. And why did he murder him? Because his own actions were evil and his brother’s righteous. So don’t be shocked, beloved brothers and sisters, if you experience the world’s hatred. Yet we can be assured that we have been translated from spiritual death into spiritual life because we love the family of believers. A loveless life remains spiritually dead. Everyone who keeps hating a fellow believer is a murderer, and you know that no murderer has eternal life residing in him.
