“For Christ has already accomplished the purpose for which the law was given. As a result, all who believe in him are made right with God” (Romans 10:4 NLT).

CHRIST, THE END GOAL OF THE LAW
Romans chapter 9 explained how God chose the Jews according to His own mercy and divine will, not according to any willing or working on their parts (Rom. 9:16). Now in chapter 10, Paul explains that even though God had selected the Jews to receive His law, and even more, that they were selected to be the people to which the Promised Seed, Jesus Christ, was given, this special selection of God did not negate the requirement that they must believe in Christ in order to be saved. Their selection did not negate their responsibility to believe.
 
Now everyone, whether Jew or Gentile, can be made right with God through faith in Christ Jesus, His Son.
