Romans 10:9-10 lays out a formula for salvation of confessing Jesus as Lord and believing that he was raised from the dead.  Our culture has turned our words into things we say but don't really stand behind and belief into wishful thinking but that is not what Paul was talking about.  He describes life-changing belief and obedience to our Lord even at great cost.  Works of obedience do not earn salvation but they are a natural consequence of saving faith.

From the end of Romans 8 through 9, Paul launches into a series of hypothetical questions and answers regarding God's justice in calling some and not others.
