If you know that he is righteous, you know that everyone who practices righteousness is born of him.

 2:1-2 My little children, I am writing these things to you that you may not sin. But, if anyone does sin, we have one who will plead our cause to the Father, Jesus Christ the righteous. For he is the propitiating sacrifice for our sins, and not for ours only but also for the whole world.
