Anyone can separate and pluck-out Bible verses, miss the context, and then wonder what in the world they mean. One of many examples is found in the first three chapters of the book of Romans. Paul was taking chapters to explain how the entire world had fallen short of God’s glory because of sin—whether Jew or Gentile. But in these passages, he also reveals the good news of God’s righteousness and acceptance being made available as a gift by a source known as faith, which occurs apart from the works of the law of commandments which came through Moses.
So whether one was a Jew under law or a Gentile without the law, all fell short, and all now have the same access to God by faith in Jesus Christ. But right-standing with God has never been attained or based upon what one does.
