What are some lessons from the Book of Genesis?

from the old testament

• Genesis opens with the creation account. While it shows that God created in six days, it emphasizes the creation of the first man and woman in the Image of God (Genesis 1:26–27). Adam and Eve were originally without sin (Genesis 1:31), created to rule over God’s creation, and to multiply and fill the earth (Genesis 1:28).
• The creation account shows that God made us in His image and breathed life directly into Adam (Genesis 2:7), a creative act that sets us apart as unique among creation. We are not simply advanced animals but were charged with ruling over them (i.e., Genesis 1:28; 2:19–20). The first woman was fashioned from a part of the man (Genesis 2:21–22), showing that men and women are created in God’s image (Genesis 1:27). God created men and women with complementary distinctions so that the two could become one in marriage, fulfilling their roles together in union with each other (Genesis 2:24).
• Genesis also shows how sin and death entered the world through Adam and Eve's rebellion (Genesis 3:1–6, 3:17-19). However, while pronouncing judgment, God included hope for humanity: “And I will put enmity Between you and the woman, And between your seed and her seed; He shall bruise you on the head, And you shall bruise him on the heel” (NASB, Genesis 3:15). This was the first gospel, a promise that unfolds in the rest of the Bible.
• Genesis 6 and 7 recount the increasing wickedness of people until God punished them through a flood, preserving only Noah and his family (Genesis 6:5-18; 7:23). The seed promised in Genesis 3:15 was preserved in Noah’s line.
• Not long after the end of the flood, human beings fell into unrepentant sin again, gathering against God, refusing to multiply and fill the earth (Genesis 11:1–4). God intervened, changing their languages so they could no longer work together and were forced to scatter (Genesis 11:5–9).
• God also intervened by speaking directly to the pagan Abram (later known as Abraham), telling him to leave his land and go to the land God had promised (Genesis 12:1–3). God promised Abraham that he would be the one through whom the righteous seed would come (Genesis 22:18) and a blessing to all nations (Genesis 12:3; 15:5–6). God accomplished this through the miracle of giving Abraham and Sarah a son despite their advanced ages (Genesis 21:1–2).
• The rest of Genesis traces the promise to Abraham through his son and grandson, Isaac and Jacob (Genesis 26:3–4; 28:13–14). Moses recounts how the twelve tribes of Israel came to be through Jacob (Genesis 29:31–30:24; 35:22–26).
• Moses singled out two of Jacob's children: Judah and Joseph. Judah acted unrighteously (Genesis 38:15–18) but repented of his sin (Genesis 38:26, 44:33-34) and received Israel’s blessing (Genesis 49:8–10). Part of that blessing was that “the scepter shall not depart from Judah” (Genesis 49:10a), an early reference to the Messiah (the seed) coming through Judah.
• The other featured son is Joseph. Through him, God preserved the heads of the twelve tribes through a severe famine (Genesis 50:20). It also provides the initial explanation for how Israel ended up in Egypt, a story which the next book, Exodus, picks up and expands.

from the new testament

• Genesis explains humanity’s need for a Savior. Jesus is the seed promised long ago in Genesis 3:15. Matthew opened his gospel by tracing Jesus’ lineage back to Abraham (Matthew 1:1–2). Paul, understanding this, said, “Now the promises were spoken to Abraham and to his seed. He does not say, ‘And to seeds,’ as referring to many, but rather to one, ‘And to your seed,’ that is, Christ,” directly calling Jesus the promised seed (Galatians 3:16, NASB).
• Not only was Jesus the Jewish Messiah, but He brought salvation for all. Paul said, “It is those of faith who are the sons of Abraham. And the Scripture, foreseeing that God would justify the Gentiles by faith, preached the gospel beforehand to Abraham, saying, ‘In you shall all the nations be blessed.’ So then, those who are of faith are blessed along with Abraham, the man of faith” (Galatians 3:7–9).

implications for today

Sixteen hundred years to write, forty different authors, three different languages. We might expect a book with those stats to be chaotic and incoherent. But the Bible isn't. In fact, it all fits so perfectly together that it points to divine authorship. The very first book sets the stage for the others. It shows us who God is. It shows us who we are and how we fell into sin and death. It also reveals God's redemptive plan to save us (Genesis 3:15).

Sometimes, Christians are accused of focusing mainly on the New Testament and ignoring the Old. Those criticisms could be right. Though the gospels draw us because they tell us of Jesus' ministry, the Old Testament, including Genesis, points to Him.

That's why it's so important that we read Genesis and share it with others: It tells us that God is always in control, even when we make a mess of things. It also shows us God's love and mercy.
