“For I speak to you Gentiles, inasmuch as I am the apostle of the Gentiles, I magnify mine office” (Romans 11:13).
Friend, may you come to know your apostle as God wants you to know him!
Who is your apostle? The average preacher or church member, if not silent, will say, “I follow the 12 apostles….,” “I follow Jesus…,” or “My apostle is my preacher.” Very rarely will they give you the correct answer—today’s Scripture.
Jesus Christ, “the Word” (John 1:1,14), the Godhead Spokesman, speaks on behalf of God the Father and God the Holy Ghost. Not many people know, however, His earthly ministry was to the nation Israel, not us Gentiles. Matthew 15:24 says: “I am not sent [apostello] but unto the lost sheep of the house of Israel” (To wit, Jesus said, “I am not the Apostle of you Gentiles. I am the Apostle of the Jews.”—cf. Hebrews 3:1) The 12 Apostles were sent to Jews, not to Gentiles: “These twelve Jesus sent forth [apostello], and commanded them, saying, Go not into the way of the Gentiles, and into any city of the Samaritans enter ye not: But go rather to the lost sheep of the house of Israel” (Matthew 10:5,6).
Years later, in Acts chapter 9, outside Damascus, the resurrected, ascended, and glorified Jesus Christ commissioned Paul to go to us Gentiles. Hence, Paul is “the apostle [apostolos—“sent one”] of the Gentiles” (today’s Scripture). Acts chapter 26 documents Christ’s words to Paul: “ But rise, and stand upon thy feet: for I have appeared unto thee for this purpose, to make thee a minister and a witness both of these things which thou hast seen, and of those things in the which I will appear unto thee;  Delivering thee from the people, and from the Gentiles, unto whom now I send [apostello] thee,  To open their eyes, and to turn them from darkness to light, and from the power of Satan unto God, that they may receive forgiveness of sins, and inheritance among them which are sanctified by faith that is in me.”
While all of the Bible is for us, Paul’s epistles, Romans through Philemon, are to and about us Gentiles (and members of the Church the Body of Christ)! source
