Abraham's Four Seeds is a biblical examination of the presuppositions of Covenant Theology and Dispensationalism. Pastor, evangelist, and author John G. Reisinger demonstrates how a correct understanding of Abraham's seeds is key to harmonizing Scripture. He writes: The following statement, if correctly understood, will help to clear up a lot of confusion: The nation of Israel was not the 'Body of Christ,' even though the Body of Christ is indeed the true 'Israel of God.' Covenant Theology cannot accept the first part of that statement and Dispensationalism cannot accept the second part.
The basic presuppositions of Covenant Theology make it mandatory that Israel be the church and be under the same covenant as the church, and the one thing a Dispensationalist must maintain is the church's present and future distinction from Israel which makes it mandatory that Israel and the church can never be under the same covenant or inherit the same blessings. What is essential to one system is anathema to the other system. Dispensationalism cannot get Israel and the church together in any sense whatever, and Covenant Theology cannot get them apart. Dispensationalism cannot see that the church is the true Israel of God and the fulfillment of the promises that God made to Abraham and the fathers, and Covenant Theology cannot see that the church, as the Body of Christ, did not, and simply could not, exist in reality and experience until the personal advent of the Holy Spirit on the Day of Pentecost.
Dispensationalism insists that Israel and the church have totally different promises and destinies (one earthly and the other heavenly), and Covenant Theology insists that Israel and the Body of Christ are equally the "same redeemed church under the same 'covenant of grace' and governed by the same identical 'canon of conduct.'" Dispensationalism drives a wedge between the OT and the NT and never the twain shall meet as specific promise (OT) and identical fulfillment (NT); and Covenant Theology flattens the whole Bible out into one covenant where there is no real and vital distinction between either the Old and New Covenants or Israel and the church.
The Old Covenant proved one's guilt and forbade one to draw near without a perfect righteousness or an acceptable sacrifice. The New Covenant declares a believer to be both righteous and acceptable in God's sight, and it bids him come boldly without fear into the very Most Holy place that was totally closed off to all but Aaron under the Old Covenant.
The law as a legal covenant ended when the veil of the temple was rent from top to bottom, and the law as a pedagogue over the conscience was dismissed on the day of Pentecost when the 'promise of the Father' took up his abode in every believer as the personal Vicar of the ascended Lord. The giving of the Spirit is the proof of the accepted work of Christ in the heavenly tabernacle, and the 'given Spirit' indwelling the believer is the indelible assurance of our eternal acceptance by the Father. It is the author's desire that this book would be of benefit to those who desire to understand "What does the Scripture say?" May the watchword Sola Scriptura have real meaning in the church!
