I use to do construction and I remember my boss telling me that if you get something plumb, straight up and down, then it would go all the way up to the moon forever. But if you get it wrong by just a little bit than you are going to be off by a lot in the end. What you do in the beginning has a big impact on where you end up. It is the same with the Bible. The book of Genesis is very foundational. Without a good grasp of Genesis the rest of our theology will likely crumble to the ground and be worth nothing. So much is built on it. If we are off here, we are going to be way off down the road of the Bible.
There are many “plot conflicts” in the book of Genesis. They will serve as our compass to find our way through the huge book that is Genesis. Leland Ryken has wisely said “Stories are always built around plot conflicts. These conflicts progress toward some type of resolution… Noting plot conflicts is one of the best ways to organize a story, either in the actual process of reading or when talking about the story” (How to Read the Bible as Literature, 41). So, there are three things I want to pay careful attention to and note their expansion in the rest of Scripture and their fulfillment through or in Jesus the Christ.
Here are a few of the themes that are the building blocks of the theology of Genesis (NDBT, 140) and in many ways the whole Bible: (1) The promise of seed, i.e. offspring, (2) the promise of land, and (3) the promise of being a blessing to the nations (see esp. 12:1-3). All of these themes are in embryonic form in Genesis chapter three and expand through the rest of the book. They continue to expand through the Old Testament but don’t find their true fulfillment until the New Testament and the coming of the Promised One. Truly, even then, in the New Testament, there is still an element of the “not yet” until in Revelation all things are made new.
