1 John 3:10-13

J.B. Phillips New Testament

¹⁰ Here we have a clear indication as to who are the children of God and who are the children of the devil. The man who does not lead a good life is no son of God, nor is the man who fails to love his brother.

^11-13 For the original command, as you know, is that we should love one another. We are none of us to have the spirit of Cain, who was a son of the devil and murdered his brother. Have you realised his motive? It was just because he realised the goodness of his brother’s life and the rottenness of his own. Don’t be surprised, therefore, if the world hates you.
