It is highly touted among those who "rightly divide the word of truth", rightly so, to divide and keep separate the scriptures where differences are recognizably identifiable and where God Himself differentiates between two or more things. Pauline dispensationalist, I being one of them, correctly understand the church, the body of Christ began with the salvation and apostleship of Paul in Acts 9. There clear indicators of the un-prophetic nature and inconsistent fulfillment of Israel's program with what God did with Paul. According to Daniel 9 and other prophets, as well as, the Psalms described what was going to shortly begin after the resurrection of Christ and even shorter still when He would sit at the Father's own right hand. He would eventually stand, just as Stephen saw and commence the long awaited day of wrath starting with the beginning of sorrows. Instead He stood up and saved His chief enemy Paul and commenced His mystery purpose. Although this is true and needs to be properly understood. However, based upon this "right division of the word of truth" many fail to properly understand the beginning of Paul's ministry and end up dividing things they shouldn't and that Paul never does. They divide things so much as if the dispensation of grace took place and is taking place in a vacuum. Division of things that Paul explains as cohesive or parallels, similar features between "time past" to "but now".
Many have failed to clearly describe the commencement of Paul's ministry. A failure to recognize that although the time that would begin with Paul's salvation and ministry was a mystery not all the content was or is. It is here where confusion still lingers, where things are divided that ought not, and thereby effect the foundation of their edification, as well as, things to be understood later on in Paul's epistles.
Let us dare to think a moment that when Paul began His ministry, although the prophetic promises were no longer being fulfilled, the dispensation of grace came into effect, and the timing was a mystery the content of the mystery Paul did not completely possess. What did he possess, especially as he entered the Jewish Synagogue's? He possessed the Old Testament scriptures (Genesis-Malachi). In fact if many of us "grace believers" lived back during the start of the dispensation of grace we wouldn't probably even listen to Paul with all his Old Testament!!! Although, Paul didn't become the fulfiller or an extension of Christ's ministry as a minister of the circumcision for the truth of God, to confirm the promises made unto the fathers...Paul was a minister of Jesus Christ to the Gentiles, ministering the gospel of God, that which can be found in and promised afore by His prophets in the holy scriptures. Therefore Paul is actually ministering something promised by Jewish prophets to the circumcision and uncircumcision; that is, the gospel of God.
Do you know what the gospel of God is? Do you know the gospel of God is what Paul begins to minister not only at the beginning of his ministry, but also in beloved book of Romans. This gospel of God is the gateway of cohesiveness and similarity between the two programs and the general framework of the right division of God's Word. In other words, the gospel of God is not something you want to divide, unless you dare be not minister to by your apostle Paul that is separated unto this very thing.
Have you ever come across Paul referring either by direct quote, or reference to something in Genesis - Malachi? Have you ever heard a grace pastor or teacher who utilizes Genesis - Malachi when their specific text is in Paul's epistles? Well whether you know it or not, or they know it or not, this is because of the gospel of God. It is interesting most (not all) things that people classify as interdispensational fall under the umbrella of "the gospel of God". If we are to rightly divide the word of truth and recognize the differences what does this imply we do with the similarities? What do we do with the things Paul quotes from the Genesis - Malachi? Why is he even doing so? It all has to do with understanding "the gospel of God" and out of it is birthed properly in your mind how right division and gathering together all things in Christ can coexist or both be true, necessary, and needful. The question becomes what falls into "the gospel of God" and what ought to be rightly divided? It is here where much confusion and controversy has resulted the past few years in the grace camp as so many often call it. The controversy has been twofold from the writers (that's me Pastor Josh) perspective: heirs and joint-heirs, and the relation of Proverbs to Paul's epistles if there be any. Both have their remedy in "the gospel of God" and it is no surprise that controversy has boiled over because this matter has been neglected.
