Paul is the Prisoner of Jesus Christ for Gentiles

Ephesians 3:1-9 -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 that by 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 the mystery of 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; That the Gentiles should be fellow-heirs, and of the same body, and partakers of his promise in Christ by the gospel: Whereof I was made a minister, according to the gift of the grace of God given unto me by the effectual working of his power. Whereof I was made a minister, according to the gift of the grace of God given unto me by the effectual working of his power.

Unto me, who am less than the least of all saints, is this grace given, that I should preach among the Gentiles the unsearchable riches of Christ And to make all men see what is the fellowship of the mystery, which from the beginning of the world hath been hid in God, who created all things by Jesus Christ:

Paul is the Master Builder for the Gentiles

1 Corinthians 3:10
According to the grace of God which is given unto me, as a wise master-builder, I have laid the foundation, and another buildeth thereon. But let every man take heed how he buildeth thereupon.

Peter points out the importance of Pauls’s Mysteries.

2 Peter 3:15 and 16 And account that the longsuffering of our Lord is salvation; even as our beloved brother Paul also according to the wisdom given unto him hath written unto you; As also in all his epistles, speaking in them of these things; in which are some things hard to be understood, which they that are unlearned and unstable wrest, as they do also the other scriptures, unto their own destruction.

Even Peter found Paul’s Mysteries in his epistles hard to understand. But warned us of ignoring them, “unto their own destruction. So as to all mysteries of the bible God expects us to believe it.

Deuteronomy 29:29 The secret things belong unto the LORD our God: but those things which are revealed belong unto us and to our children forever, …

In ending, even though Paul and Peter had their differences, Peter refers to Paul as “beloved brother Paul”. They both knew their Jobs in Christ. Paul was to Gentiles and Peter was to the Jews. The message “Faith unto Salvation” was the same in line with the purpose of God’s Word – the Bible
