1. Was the mystery revealed only to Paul? No. The mystery was revealed to Paul,and to the apostles and prophetsby the Spirit.
Ephesians 3:1-5 For this cause I Paul, the prisoner of Jesus Christ for you Gentiles, If ye have heard of the dispensation of the grace of God which is given me to you-ward: How thatby revelation he made known unto me the mystery;(as I wrote afore in few words, Whereby, when ye read, ye may understand my knowledge in themysteryof Christ) Which in other ages was not made known unto the sons of men,as it is now revealed unto his holy apostles and prophets by the Spirit;
2. What was the mystery?
Ephesians 3:6That the Gentiles should be fellow heirs, and of the same body, and partakers of his promise in Christ by the gospel:
3. Paul refers to the samemysteryhere . . .
(Romans 16:25-26) Now to him that is of power to stablish you according to my gospel, and the preaching of Jesus Christ, according tothe revelation of the mystery, which was kept secret since the world began, But now is made manifest, and by the scriptures of the prophets, according to the commandment of the everlasting God, made known to all nations for the obedience of faith:
4. This truth is also proclaimed by Peter, who tells us (a) to whom, (b) where, and (c) when it began to be published.
Acts 10:34-45 Then Peter opened his mouth, and said, Of a truth I perceive that God is no respecter of persons: But in every nation he that feareth him, and worketh righteousness, is accepted with him. The word which God sent unto the children of Israel, preaching peace by Jesus Christ: (he is Lord of all:) That word, I say, ye know, which was published throughout all Judaea, and began from Galilee, after the baptism which John preached;How God anointed Jesus of Nazareth with the Holy Ghost and with power: who went about doing good, and healing all that were oppressed of the devil; for God was with him. And we are witnesses of all things which he did both in the land of the Jews, and in Jerusalem; whom they slew and hanged on a tree: Him God raised up the third day, and shewed him openly; Not to all the people, but unto witnesses chosen before of God, even to us, who did eat and drink with him after he rose from the dead. And he commanded us to preach unto the people, and to testify that it is he which was ordained of God to be the Judge of quick and dead. To him give all the prophets witness, that through his name whosoever believeth in him shall receive remission of sins. While Peter yet spake these words, the Holy Ghost fell on all them which heard the word. And they of the circumcision which believed were astonished, as many as came with Peter, because that on the Gentiles also was poured out the gift of the Holy Ghost.
5. The law was given by Moses, but grace and truth came by Jesus Christ.
John 1:16-17 And of his fullness have all we received, and grace for grace. For the law was given by Moses, but grace and truth came by Jesus Christ.
Galatians 3:6-14 Even as Abraham believed God, and it was accounted to him for righteousness. Know ye therefore that they which are of faith, the same are the children of Abraham. And the scripture, foreseeing that God would justify the heathen through faith, preached before the gospel unto Abraham, saying, In thee shall all nations be blessed. So then they which be of faith are blessed with faithful Abraham. For as many as are of the works of the law are under the curse: for it is written, Cursed is every one that continueth not in all things which are written in the book of the law to do them. But that no man is justified by the law in the sight of God, it is evident: for, The just shall live by faith. And the law is not of faith: but, The man that doeth them shall live in them. Christ hath redeemed us from the curse of the law, being made a curse for us: for it is written, Cursed is every one that hangeth on a tree: That the blessing of Abraham might come on the Gentiles through Jesus Christ; that we might receive the promise of the Spirit through faith.
CHRISTMAS…For if he that cometh preacheth another Jesus, whom we have not preached, or if ye receive another spirit, which ye have not received, or another gospel, which ye have not accepted, ye might well bear with him. 2 Corinthians 11:4
