The theological purposes of Genesis, chapters 1-11 are seen from two main perspectives.
You begin with God in His place as the creator. This is the all-important fact that will guide our understanding through the remainder of the book of Genesis. We see God as the creator when we read, “In the beginning, God created” (Genesis 1:1) and this theme will follow us through the remainder of the Old Testament all the way to the Revelation of Jesus to the apostle John. In his gospel John picks up this same baton, pointing out to us that it was Christ that was in the beginning and involved in creation. In the final book of the New Testament, Jesus speaking again makes clear that He was in the beginning and the end, the Almighty God. (Revelation 1:8)
This knowledge given to us must guide our understanding throughout the rest of scripture. We are created by God, and as such are responsible to obey His commands. Which brings us closer home.
The second perspective is that of rebellion and redemption. The realization that we are merely created beings seems to drive man crazy, and his desire is to change this shift. Man wants to see himself as the authority. Hamilton does a great job giving us clarity to this when he explains the reason that the knowledge of good and evil was enticing to Eve. In his book, One might then suggest that “the knowledge of good and evil” is moral autonomy. In deciding for themselves what is good and proper and what is not, the couple are making themselves the final moral authority for their lives (in a diabolical way becoming their own god) and “stepping out of the position of creaturely dependence and trust in the creator” (Hamilton, 31)
The beauty in this rebellion is the redemption had already been the plan in place to rescue man from his inevitable rebellion. Adam and Eve rebelled but they found grace in God clothing them and giving them the promise of the gospel (Genesis 3:15; 21). The earth again rebelled, but grace was extended to Noah (Genesis 6:8). The hope of the gospel extends to us today! The gospel extends to us the ability to not only be a redeemed creation but a restored creation. Through Christ we are as intended to be “more than simply representative, human beings are representational of the invisible God.” (Hamilton, 28) We have the promise of being conformed into the image of Christ, through the work of the Spirit. (Romans 8:29)
This is how these chapters relate to the rest of scripture as this redemptive story is played out again and again. That God has created man in his image and sent His Son to take on this image of created man so that they could be again conformed into the image of His Son.
