Romans  2:12-20 (NLT)

12-16 (Direct Quote) “When the Gentiles sin they will be destroyed, even though they never had God’s written law.  And the Jews who do have God’s law, will be judged by that law when they fail to obey it.  (13) For merely listening to the law doesn’t make us right with God.  It is obeying the law that makes us right in his sight.  (14) Even the Gentiles, who do not have God’s written law show that they know his law when they instinctively obey it, even without having heard it.  (15) They demonstrate that God’s law is written in their hearts, for their own conscience and thoughts either accuse them or tell them they are doing right. (16) And this is the message I proclaim—that the day is coming when God, through Jesus will judge everyone’s secret life.”

17- (Direct quote) “You who call yourselves Jews are relying on God’s law, and you boast about your special relationship with him. (18) You know what he wants; you know what is right because you have been taught his law. (19) You are convinced you are a guide for the blind and a light for people who are lost in darkness. (20) You think you can instruct the ignorant and teach children the ways of God.  For you are certain that God’s law gives you complete knowledge of the truth.” 

I don’t know that this was the best stopping point today to get the full meaning of what Paul was trying to say here, but I didn’t know how else to break it up, without finishing the entire chapter, and I said I would only do 10 verses at time.  I just wanted to note here, that in order to understand completely what is being said, you need to read the letter as a whole, and not break it up the way I am doing.
