Being a Jew has no value in and of itself. The heart must be right with Elohim. The prophet Isaiah spoke the Words of Elohim concerning the people of Israel who merely go through the motions (Isa. 1:11-15). But Paul is going to answer the question: What is the advantage of being a Jew? There is no salvation in being a member of a particular group or race, even in being a Jew. But there are some benefits and a great history with the Father.
What does Paul mean here by being “set apart to the Gospel of Elohim?” He means that he has passed beyond the things of the world and is totally dedicated to the message of Yeshua Messiah. Paul is not longer living for the Talmudic teachings that he learned most of his life. He is now dedicated to spreading the message of Messiah, teaching the ways of Elohim (His Torah), and separated from the traditions of man.
