3Everyone who has this hope set on him purifies himself, even as he is pure.
4Everyone who sins also commits lawlessness. Sin is lawlessness.
5You know that he was revealed to take away our sins, and in him is no sin.
6Whoever remains in him doesn’t sin. Whoever sins hasn’t seen him, neither knows him.
7Little children, let no one lead you astray. He who does righteousness is righteous, even as he is righteous.
9Whoever is born of God doesn’t commit sin, because his seed remains in him; and he can’t sin, because he is born of God.
10In this the children of God are revealed, and the children of the devil. Whoever doesn’t do righteousness is not of God, neither is he who doesn’t love his brother.
11For this is the message which you heard from the beginning, that we should love one another;
12unlike Cain, who was of the evil one, and killed his brother. Why did he kill him? Because his works were evil, and his brother’s righteous.
13Don’t be surprised, my brothers, if the world hates you.
15Whoever hates his brother is a murderer, and you know that no murderer has eternal life remaining in him.
19And by this we know that we are of the truth, and persuade our hearts before him,
20because if our heart condemns us, God is greater than our heart, and knows all things.
21Beloved, if our hearts don’t condemn us, we have boldness toward God;
23This is his commandment, that we should believe in the name of his Son, Jesus Christ, and love one another, even as he commanded.
