1 John 3:10-12

Revised Geneva Translation

¹⁰ In this are the children of God and the children of the devil known. Whoever does not practice righteousness is not of God, nor is the one who does not love his brother.

¹¹ For this is the message that you heard from the beginning: that we should love one another;

¹² not as Cain, who was of the wicked one and killed his brother. And why did he kill him? Because his own works were evil and his brother’s good.
