No, Paul did not bring a new message. Paul brought clarity to the one gospel message of Jesus Christ. (It has always seemed silly, the very notion there's some gospel of Christ and another of Paul, when Christ gave Paul His gospel to give to the world, in the first place, Galatians 1, without the likes of parables, is all. Paul refuted such notions himself, 1 Corinthians 1:12-13, as, two millennia later, we nonetheless wallow in the -isms of man. Ecclesiastes 1:9.)
Faith, atonement by faith in the flesh and blood sacrifice of Jesus Christ, the new birth and coming of the Spirit, that all men would be drawn to the cross and gospel of Christ, the second coming, even the church in His parables: Christ taught all these things. Christ taught the same eschatology, simply expanded upon after the four gospel books and, ultimately, in Revelation.
I would not trade coming to the place in life of a peace that is beyond sublime, every day, to understand that the Bible, from cover to cover, is Jesus Christ, an unfolding, harmonious, consistent unfolding of one message and revelation of one God, in three Persons. I sincerely feel sorry for anybody who doesn't see the remarkable, supernatural unity of God's word down the ages, or the unity of God, the clarity and peace of that harmony, and it's sorry to see so many, filled with devilish venom and rancor, who claim they're "rightly dividing" the word of God who are, in fact, taking an assembled puzzle and scattering the pieces, slicing and dicing until there's even no whole Bible, no whole gospel, context left.
Hence the endless disputes and confusion, all the -isms of man, where nobody agrees and everybody is right, at the same time, et al, as if there are conflicting truths, as if the Bible doesn't contain John 16:13, begging, screaming the question as to where the Holy Spirit is failing many of you, claiming conflicting truths? And, of course, this a rhetorical question, as the Spirit does not fail, leave it to each to come to their own conclusion, therefore.
Have any of you noticed how many great, Christian men of God there have been, down the generations, who, in fact, agree on truths you're disputing every day? Is there anybody here who has seen the supernatural harmony among those truly of the Spirit? Granted, they are not as many as in the Encyclopedia of Philosophy of the world, or as there are Catholic, Mormon, Adventist, Armstong, Hebrew roots, Calvinist functionaries, whatever, ad infinitum, at least names in the public eye, but I could fill a large room with men, many gone on to be with the Lord, some still living, largely sincere seminarians, dedicated to a life pursuing the truth of the Lord, who weren't educated in scripture on a message board, by a cult denomination, by a deceiving tare or conspiracy website, who'd agree on each and every fundamental point of the gospel, and complexities less fundamental, which most all of you disagree on. They of peace and one message, you all over the place, at each others’ throats, for page after page, every day.
Just a thought that, sorry, is sure to get a lot of knees jerking, albeit this the stark truth, proven in something called a thread around here. Also sorry, but the fact is, I could find a long list of real theologians of spotless reputations who agree and would all dispute most of what you see here, as to dispensations, starting with Harry Ironside, who, himself, was a dispensationalist. To whit:
H. A. Ironside, a strong dispensationalist himself, wrote a good booklet outlining some of the dangers of ultra-dispensationalism. In it he says that he has "no hesitancy in saying that [ultra-dispensationalism's] fruits are evil. It has produced a tremendous crop of heresies throughout the length and breadth of this and other lands; it has divided Christians and wrecked churches and assemblies without number; it has lifted up its votaries in intellectual and spiritual pride to an appalling extent, so that they look with supreme contempt upon Christians who do not accept their peculiar views [sound familiar, TOL?]; and in most instances where it has been long tolerated, it has absolutely throttled Gospel effort at home and sown discord on missionary fields abroad. So true are these things of this system that I have no hesitancy in saying it is an absolutely Satanic perversion of the truth" (Wrongly Dividing the Word of Truth, chapter 1, Loizeaux Brothers, 1938).
In fact, the only use of dispensations is that of a tool to divide the unfolding revelation of God to man, His progressive program, in time, solely like making a diagram, proper use of dispensations doctrinally neutral of the truths of scripture. Dispensations are not and have never been their own cult, as they were conceived. You are no more true dispensationalists than cults are true Christianity.
