As you continue to read critically, you start noticing that Paul was not preaching the same Gospel that Jesus preached. He always refers to the message he preaches as; MY GOSPEL. In fact Paul’s Gospel does not reflect the Gospel that the 12 apostles preached after the death of their Teacher-Jesus.
That isn't true. Paul uses the term "good news of" (gospel of) in a variety of ways just as the other writers did.
Gospel of Jesus Christ (or Christ ) – 12 times
Gospel of God – 7 times
Gospel of the kingdom – 4 times
Gospel of peace – 2 times
Gospel of the grace of God – 1 time
Gospel of your salvation – 1 time
Gospel of the uncircumcision – 1 time
Gospel of the circumcision – 1 time
Gospel of his Son – 1 time
The Watchtower focuses their entire message on the “good news of the kingdom”. Of course the “kingdom”, as explained by the Watchtower is really just another name for themselves (the visible part therof) in their way of thinking. It is repeated so often in Jehovah’s Witness circles that many will go to the extent and say that the bible is a book of government….. which they are quick to point out refers to their own ecclesiastical authority in modern times.
However, an examination of the term “good news of ____” (or gospel of ____) reveals that by far it is the good news of Jesus that is most frequently referred to in the New Testament. In fact, out of the thirty times it occurs, only four of the occurrences are “gospel of the kingdom”.
Jesus was sent to the Jews only and he presented himself as their King. He was the good news of the kingdom. Of course the Jews rejected this good news and so the Gentiles were offered it as well shortly after Jesus was resurrected. Because the Gentiles had no legal contract with God like the nation of Israel did, the "good news" took on an expanded scope which included salvation for the gentiles.
Peter, James and John, the three most influential apostles were in agreement with Paul's message ...as Galatians 2 verifies:
Then fourteen years after I went up again to Jerusalem with Barnabas, and took Titus with me also. 2And I went up by revelation, and communicated unto them that gospel which I preach among the Gentiles, but privately to them which were of reputation, lest by any means I should run, or had run, in vain. 3But neither Titus, who was with me, being a Greek, was compelled to be circumcised: 4And that because of false brethren unawares brought in, who came in privily to spy out our liberty which we have in Christ Jesus, that they might bring us into bondage: 5To whom we gave place by subjection, no, not for an hour; that the truth of the gospel might continue with you. 6But of these who seemed to be somewhat, (whatsoever they were, it maketh no matter to me: God accepteth no man's person:) for they who seemed to be somewhat in conference added nothing to me: 7But contrariwise, when they saw that the gospel of the uncircumcision was committed unto me, as the gospel of the circumcision was unto Peter; 8(For he that wrought effectually in Peter to the apostleship of the circumcision, the same was mighty in me toward the Gentiles:) 9And when James, Cephas, 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, and they unto the circumcision. 10Only they would that we should remember the poor; the same which I also was forward to do.
