the earthly and heavenly purposes of God, which reach on into eternity

Scripture is too subtle for the guy who is in the spiritual condition of
the natural man who does not discern the things of the Spirit in I
Corinthians 2: 14.. So dispensationalism or Christian Zionism changed the
interpretation of the Bible to supposedly make it consistent with a
theology honoring the chosen people by their physical bloodline.
That which is physical is easier for the carnal mind to grasp.
Briefly, here are the founders of dispensationalism-Christian Zionism:
To counteract the Protestant teaching that the Pope was the anti-Christ, Francisco Ribera,1537-1591, a Jesuit, wrote in 1585 a commentary on the Book of Revelation - Sacrum Beati Ioannis Apostoli, & Evangelistiae Apocalypsin Commentarij.
Ribera said that the anti-Christ would be one man, would rule for three and a half literal years, would deny Christ,persecute the saints, rebuild the temple in Jerusalem, conquer the world and kill the Two Witnesses of God. In 1585 the Catholic Church was into amillennialism which does not emphasize futurist prophecy fulfillment. But the Jesuit Ribera was teaching futurism.
Later, a Jesuit, Manuel or Emmanuel de Lacunza, 1731-1801, wrote The Coming of Messiah in Glory and Majesty. Lacunza, like Ribera, goes beyond the amillenial theology of the Catholic Church. He said that the Church would be raptured before Jesus returned to Earth.
Lacunza said that the appearance of the ant-Christ and the two witnesses are still in the future, just before the coming of Christ. For Lacunza the prophecies concerning the antichrist will be fulfilled just prior to the coming of Christ. He said the tribulation during which the church will be persecuted by the antichrist will last 1260 literal days.
Edward Irving, 1792-1834, became interested in Lacunza's ideas and translated his book into English. Irving was interested in the teachings of Lacanza before John Darby began to take up these ideas.
John N. Darby, founder of the Plymouth Brethren, admitted that he had been influenced by the writings of the Jesuit De Lacunza.
Then an American, Cyrus Ingerson Scofield, 1843-1921, spread what came to be called dispensationalism in the English speaking world, especially through his book, the Scofield Reference Bible in 1909.
Lewis S. Chafer, 1871-1952, another American, made the teachings of Ribera, Lacunza, Irving, Darby,and Scofield into a more systematic theology. Chafer also founded Dallas Theological Seminary.
So, it was John Darby and C. I. Scofield and Lewis S. Chafer who "changed the Bible from being a mass of more or less conflicting
writings into a classified and easily assimilated revelation of both
the earthly and heavenly purposes of God." What they did was change the interpretation of the Bible. Their interpretation of the Bible emphasized Jewish supremacy, and the continuation of the Old Covenant in some way. They postulated that God now has two peoples, Old Covenant Israel - which Chafer calls earthly Israel - and the Church.
