What is the purpose of Genesis? If I asked you this what would you tell me? I recently asked a friend about this and this was his response, “The story of our beginning, of creation.” I responded and said that he was not wrong, creation is in there for sure, but I did say that he was missing something in the grand picture of Genesis.
The grand purpose of Genesis can be seen when we notice that it was Moses who wrote the book. This matters because what else did Moses write? He wrote the entire Torah as well. Most people will say that Moses wrote Exodus through Deuteronomy to prepare the people of Israel to enter the promise land, but always exclude Genesis from this purpose believing it to be written to describe the story of creation alone. This should not be done.
I think Genesis should be included with the rest of the Torah as regards to its purpose as a whole. Therefore this means Genesis was written to prepare the people of Israel to enter into the promise land along with the other books in the Torah. How? Genesis begins with Gods people dwelling safely in Eden, is then filled with all sorts of sin, and ends with Gods people dwelling in safety in Egypt.
What then was Israel supposed to learn from Genesis? That God is still with them, that God really does keep His promises, and that God really means to encourage them as they enter the land He’s giving them. No matter what sin happens to them, around them, or even from them, God will still take them exactly where He wants them to be.
How are we to be encouraged today from the book of Genesis? Rather than merely focusing on Genesis as a scientific argument for creation over evolution, we ought to be encouraged in a somewhat similar manner to Israel. God is still with us, that God really does keep His promises, and that God really means to encourage us as we live out our lives under His gracious sovereign hand. No matter what sin happens to you, around you, or even from you, God will still take you exactly where He wants you to be. His people always dwell securely and we never need fear over anything that happens in our lives.
This is the God intended purpose of Genesis.
