And you know that Jesus came to take away our sins, and there is no sin in him.
Anyone who continues to live in him will not sin. But anyone who keeps on sinning does not know him or understand who he is.
Dear children, don’t let anyone deceive you about this: When people do what is right, it shows that they are righteous, even as Christ is righteous.
But when people keep on sinning, it shows that they belong to the devil, who has been sinning since the beginning. But the Son of God came to destroy the works of the devil.
Those who have been born into God’s family do not make a practice of sinning, because God’s life is in them. So they can’t keep on sinning, because they are children of God.
So now we can tell who are children of God and who are children of the devil. Anyone who does not live righteously and does not love other believers does not belong to God.
This is the message you have heard from the beginning: We should love one another.
We must not be like Cain, who belonged to the evil one and killed his brother. And why did he kill him? Because Cain had been doing what was evil, and his brother had been doing what was righteous.
So don’t be surprised, dear brothers and sisters, if the world hates you.
If we love our brothers and sisters who are believers, it proves that we have passed from death to life. But a person who has no love is still dead.
Anyone who hates another brother or sister is really a murderer at heart. And you know that murderers don’t have eternal life within them.
