1 John 3:10-12

Lexham English Bible

¹⁰ By this the children of God and the children of the devil are evident: everyone who does not practice righteousness is not of God, namely, the one who does not love his brother.

God is Love, so Love One Another

¹¹ For this is the message that you have heard from the beginning: that we should love one another, ¹² not as Cain, who was of the evil one and violently murdered his brother. And for what reason^[a] did he violently murder him? Because his deeds were evil and the deeds of his brother were righteous.
