Romans 1:16-17New International Version (NIV)

16 For I am not ashamed of the gospel, because it is the power of God that brings salvation to everyone who believes: first to the Jew, then to the Gentile.17 For in the gospel the righteousness of God is revealed—a righteousness that is by faith from first to last,[a] just as it is written: “The righteous will live by faith.”[b]

This verse is talking about how we have to stand up for what we believe in so others can believe. Then v17 is about how we are saved - righteousness by faith.
