5
You know that he appeared to take away sins, and there is no sin in him.
6
Every person who remains in relationship to him does not sin. Any person who sins has not seen him or known him.
Practicing sin or righteousness
7 Little children, make sure no one deceives you. The person who practices righteousness is righteous, in the same way that Jesus is righteous.
8
The person who practices sin belongs to the devil, because the devil has been sinning since the beginning. God's Son appeared for this purpose: to destroy the works of the devil.
9
Those born from God don't practice sin because God's DNA remains in them. They can't sin because they are born from God.
10
This is how God's children and the devil's children are apparent: everyone who doesn't practice righteousness is not from God, including the person who doesn't love a brother or sister.
11
This is the message that you heard from the beginning: love each other.
12
Don't behave like Cain, who belonged to the evil one and murdered his brother. And why did he kill him? He killed him because his own works were evil, but the works of his brother were righteous.
Loving each other
13 Don't be surprised, brothers and sisters, if the world hates you.
14
We know that we have transferred from death to life, because we love the brothers and sisters. The person who does not love remains in death.
15
Everyone who hates a brother or sister is a murderer, and you know that no murderer has eternal life residing in him.
