In order to understand more about righteousness, one ought to look at the life of Daniel , though he was a civil servant working for an oppressive government.
The angle of the Lord told Daniel that he was highly esteemed , meaning he was highly valued or respected by God , even though the angel had to fight a demon for 21 days in order to deliver the message to Daniel ,he was relentless in his quest because Daniel had kept on praying seaking answers from God until Michael the ark angel came to his aid.
that is what true righteousness means .
