The Apostle Paul tells us in Galatians how he traveled to meet with the Messianic Jerusalem Pentecostal Church leaders so me 14 years after his first and only other visit. Below Paul refers to his meeting in Jerusalem when he told the apostles and elders there about the unique new gospel that he had received directly from the ascended Lord Jesus (Gal 1:12).

“And I (Paul) went up by revelation and COMMUNICATED UNTO THEM (the Pentecostal Jerusalem church leaders) THAT GOSPEL (unique) WHICH I PREACH AMONG THE GENTILES,

but (I did it first) privately to them which were of reputation, lest by any means I should run, or had run, in vain…

And when James, Cephas [Peter] and John, who seemed to be pillars, perceived the grace that was given unto me, THEY GAVE TO ME AND BARNABAS THE RIGHT HANDS OF FELLOWSHIP, that we should go unto the heathen (Gk. ethnos, Gentiles), and they (would restrict themselves) unto the Circumcision [Israel]” (Gal. 2:2-9).

Here above, by agreement, Peter, James and John promised publicly to confine or restrict their ministry of “the gospel of the Kingdom” to Israel alone proclaiming "the gospel of the Kingdom" that Jesus had given them for Israel... while Paul and his co-workers went to the Gentiles with Paul’s message of “the gospel of the grace of God.” This is almost beyond belief in view of the fact that “the twelve” (not Paul) had originally been commissioned and sent by the Lord Jesus Himself into “all the world” to preach “the gospel of the kingdom.”

Can we then say Peter, James and John all out of the will of God in making this agreement? By no means!

Subsequent revelation proves that Peter, James and John were all very much in the will of God. You see, it the last straw was when Israel’s religious leaders rejected Christ by stoning Stephen to death (Act 7:58). Then God set Israel’s promised “Kingdom” aside and ushered in the new, yet eternally planned, program of God’s pure grace for the Gentiles.

God sent this new grace gospel via one new Apostle (Greek, apostolos, means “sent one”). Paul was "the Apostle to the Gentiles” (Rom 11:13). Paul’s message was called “the gospel of the grace of God” (Act 20:24) that is in effect today, during this age of “the dispensation of the grace of God” (Eph 3:2).

In the light of these Scriptures it’s difficult to understand how anyone can argue that Paul’s ministry was merely a perpetuation of that of “the twelve” with their “the gospel of the kingdom” and “the gospel of the grace of God” are the same. They certainly are not!

God intended that “The gospel of the kingdom” go to Israel first... then for Israel to bring to “all the world,” expecting the soon return of the Lord Jesus and "the Kingdom" on earth. But that message and plan of "the Kingdom" to come to earth was interrupted when Israel short-circuited their call by rejecting and crucifying Christ – the Messiah. God then set Israel's plan aside for a time. In the interim period, God turned to the Gentiles with a new Apostle, Paul, to bear the new  (never prophesied) "gospel of the grace of God." Paul here below speaks of Israel being set a side for a time and how long it will last.

“I would not, brethren, that ye should be ignorant of this mystery, lest ye should be wise in your own conceits; that Blindness In Part Is Happened To Israel, (temporarily) until The Fulness Of The Gentiles Be Come In.” (Romans 11:25)

If the above passages teach us anything clearly, they teach us the unique character of Paul’s apostleship and message. Paul devoted almost two chapters of his letter to the Galatians to the fact that he had NOT received his message from "the twelve," saying "they added nothing to me,"  rather, it was he who communicated to them.

Paul stresses the fact that those (Peter, James, et al) who had first been sent to all nations, “beginning at Jerusalem,” had now, under the guidance of the Holy Spirit, agreed to turn over their Gentile ministry to Paul so that he might proclaim far and wide his new "gospel of the grace of God” as found in Eph. 2:8-9.

“For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: 9 Not Of Works, lest any man should boast. (Ephesians 2:8-9)

“Being Justified Freely By His Grace through the redemption that is in Christ Jesus:” (Romans 3:24)
