Before continuing with a couple points related more directly to the land promise, and then going on to finish this series, I thought it would be good to address an important side issue. In the comments of part 5, it was again stated that I am wrong for going backward from the New Testament to the Old Testament. It was asserted that doing this is reading the NT back into the OT and is wrong hermeneutics. Proper exegesis takes the OT on its own basis and ignores later revelation. Such an approach, Will Dudding claimed, flows from a proper understanding of progressive revelation. At least that is what I understood him as saying in this comment.

Progressive Revelation

Progressive revelation is actually a good concept to explain at this point. And I hope to show how it bolsters my hermeneutical approach rather than invalidating it. So let’s start with revelation.

Revelation

As believers in inerrancy, and the “Sola Scriptura” of the Reformation, we uphold the Bible as the sole source of specific revelation to mankind. God has revealed what was unknowable and hidden from man, by declaring his mind to us in the words which make up the inspired Scriptures. Revelation is a gift to us, and it is not something which changes. God knows all, and He has always known what He would reveal to us. All along, God has had His plan for human history complete and settled. And He has known what He would reveal to us in the Bible. So from this perspective, revelation is similar to God opening a shut window to give us a glimpse, just the specific and intended glimpse He wants us to have, of what God has planned and will do for us.

Progressive

“Progressive” refers to the progression of revelation. As we look at Scripture, we can easily tell that God revealed more truth to David than he did to Moses, who had more truth than Abraham. And of course, we on this side of Christ have the complete revelation and thus have more access to truth than David, or even the apostles had (as the canon was completed after most of them had died). At each stage of human history, God advanced His story of redemption a little more. He revealed a little more truth until all was revealed through the advent of Christ (Heb. 1:1) and the subsequent NT writings (John 16:13-14; 14:25-26).

To go back to our analogy, as the Word of God was being written and compiled, the window of Heaven was being raised a little bit higher, and higher, until now it is fully open and we can know all of what God wills us to know. This is just an analogy, but there are explicit places in the New Testament where this idea is explained.

Scriptural Examples

The New Testament mentions that Old Testament passages were written for our learning (Rom. 15:4; Rom. 4:23; 1 Cor. 9:9-10), and OT events happened as lessons for us (1 Cor. 10:6, 11). Even more explicitly, Old Testament institutions were shadows of things to come (Heb. 8:5; 10:1; Col. 2:16-17). In Christ, the shadow is done away and the substance remains (Col. 2:17). In fact, the Old Testament scriptures testify of Christ and point to Him (John 5:39; Luke 24:27). And many Old Testament events are explained in NT gospel terms (Gal. 3:8).

What does this mean for our study? I take it to mean that all along, God knew the complete revelation of what He would do through Christ. And God as the Divine Author of all of Scripture, deliberately foreshadowed things as he orchestrated events and revealed Scriptures all of which would point to Christ and would have a more full meaning for believers in Christ, than they would for the immediate recipients of the OT Scriptures. Yet even for those Jewish believers in God, the very Scriptures they received would point them beyond their current day and work in them a faith in a coming redeemer.

Conclusion

So with respect to progressive revelation, I hold that God deliberately revealed truth in this way so as to hint at and foreshadow the more full revelation which God would ultimately provide. Just because Abraham and others only saw through a partially open window, does not mean God did not have the full picture in mind as He wrote. When God gave promises to Abraham concerning his descendants, God knew full well that the descendants he had in mind were spiritual faithful children, Jew and Gentile (Heb. 2:15; Gal. 3:29). Abraham knew there was more to the land promise than just the plot of land, for he was looking for a heavenly city (Heb. 11:10, 13-16) even as we believers in Christ do (Heb. 13:14). Abraham had great faith in God, even faith that God could raise Isaac from the dead (Rom. 4:14-22; Heb. 11:19), and he even believed the gospel as revealed to him through the promises (Gal. 3:8).

In short, because of progressive revelation, we have no warrant to ignore the full and intended meanings revealed in the New Testament, as we go back to exegete what Old Testament passages mean. Those passages were written with us in mind and for our learning and instruction.

Now of course much more could be said on this point, and I would encourage you to start with studying how the NT authors used the OT scriptures. I believe they used the OT in a legitimate fashion, intended to illustrate to us how we are to use it. Scripture is more than just a literal meaning couched in words. It has a spiritual meaning, discerned only by the work of the Holy Spirit. Just as Human authors use many literary devices and allusions to foreshadow events which are to happen later in their book, even so God can do and has done this with His book, the Bible. I’d encourage you to read this article by my friend Nathan Pitchford on the importance of reading and studying the Bible together as one unified revelation from God.
