1 John 3:10, 12, 15 So now we can tell who are children of God and who are children of the devil. Anyone who does not live righteously and does not love other believers does not belong to God. We must not be like Cain, who belonged to the evil one and killed his brother. And why did he kill him? Because Cain had been doing what was evil, and his brother had been doing what was righteous. Anyone who hates another brother or sister is really a murderer at heart. And you know that murderers don’t have eternal life within them. | New Living Translation (NLT)
