1 John 2:29

If you know that he is righteous, you know that everyone who does what is right has been born of him.

(v29, NIV)

There is a connection made between righteousness and God. Well, this may seem like a no brainer, but it is important. Those who do what is right have been born of him. Previously, John talked about a connection between the father and the son. If you deny the son, you do not have the father. You can't just deny the son and have the father. In addition, there is a connection between fathers and their children. If we truly are God's children, we will do what he says and have similarities to him as a child resembles their father. The one John is talking about here is righteousness. Righteousness is something that is apparent in those who are born of him. This is also somewhat of a test. Similar to chapter one with the contrast between light and darkness, there is a test here with regards to righteousness. If those who do what is right have been born of him, I'm guessing the opposite would be true. Those who do not do what is right, they do what is wrong and have not been born of him.
