1 John 3:10-12

New Life Version

¹⁰ This is the way you can know who are the children of God and who are the children of the devil. The person who does not keep on doing what is right and does not love his brother does not belong to God. ¹¹ This is what you have heard from the beginning, that we should love each other. ¹² Do not be like Cain. He was a child of the devil and killed his brother. Why did he kill him? It was because he did what was sinful and his brother did what was right.
