1 John 3:7-15

7Dear children, do not let anyone lead you astray. The one who does what is right is righteous, just as he is righteous. 8The one who does what is sinful is of the devil, because the devil has been sinning from the beginning. The reason the Son of God appeared was to destroy the devil’s work. 9No one who is born of God will continue to sin, because God’s seed remains in them; they cannot go on sinning, because they have been born of God.

10This is how we know who the children of God are and who the children of the devil are: Anyone who does not do what is right is not God’s child, nor is anyone who does not love their brother and sister.

More on Love and Hatred 11For this is the message you heard from the beginning: We should love one another. 12Do not be like Cain, who belonged to the evil one and murdered his brother. And why did he murder him? Because his own actions were evil and his brother’s were righteous. 13Do not be surprised, my brothers and sisters, The Greek word for brothers and sisters (adelphoi) refers here to believers, both men and women, as part of God’s family; also in verse 16. if the world hates you. 14We know that we have passed from death to life, because we love each other. Anyone who does not love remains in death.

15Anyone who hates a brother or sister is a murderer, and you know that no murderer has eternal life residing in him.
