What is the Book of Genesis about?

Genesis is the Bible's book of beginnings — the origin of the universe, humanity, sin, covenant, and the promise of redemption. In fifty chapters it moves from creation and the fall (chapters 1–11) to the patriarchal narratives of Abraham, Isaac, Jacob, and Joseph (chapters 12–50). The unifying thread is God's sovereign grace advancing his covenant promise that through Abraham's Seed all nations would be blessed — a promise fulfilled in Jesus Christ.

Who wrote the Book of Genesis and when?

Moses is the author of Genesis, writing under divine inspiration approximately 1440 B.C. Jesus attributes the Pentateuch to Moses in John 5:46. The Westminster Confession of Faith lists the five books of Moses among the canonical Scriptures. Modern documentary theories denying Mosaic authorship are incompatible with the testimony of Christ and the apostles.

What is the Protoevangelium in Genesis 3:15?

The Protoevangelium is the first gospel promise in Scripture — God's declaration to the serpent that the Seed of the woman would crush his head (Genesis 3:15). The Seed of the woman is Christ, born of a virgin, who crushed Satan's power through his death and resurrection. Every covenant promise from Abraham to David to the new covenant unfolds from this verse.

What does Genesis teach about creation ex nihilo?

Genesis 1:1 establishes creation ex nihilo — God created the universe out of nothing by the power of his word alone, not from pre-existing matter. The Hebrew verb bara is used exclusively of divine action. The Westminster Confession of Faith (4.1) affirms this directly. Creation ex nihilo is the foundation of human dignity, moral accountability, and the doctrine of providence.

What is the covenant of works in Genesis?

The covenant of works is God's arrangement with Adam in Genesis 2:15–17 — life for obedience, death for disobedience. As federal head of all humanity, Adam's failure brought guilt and spiritual death to all his descendants (Westminster Confession 6.3). Christ, the second Adam, succeeded where the first failed — his perfect obedience is the ground of justification for all who believe.

How does the Reformed tradition interpret the Fall in Genesis 3?

The Reformed tradition reads Genesis 3 as a literal, historical event with universal consequences. Adam's disobedience introduced guilt, total depravity, and spiritual death to all humanity. The Westminster Confession (6.2) states that from Adam's first sin, all his posterity became dead in sin. The logic of the atonement depends entirely on the historical reality of Adam's fall.

What is the Tower of Babel and what does it mean theologically?

The Tower of Babel (Genesis 11:1–9) is humanity's post-flood defiance of God's command to fill the earth — the culmination of Genesis 1–11's portrait of progressive rebellion. God confused their language and scattered them. Theologically, Babel sets the stage for Abraham: God's call in Genesis 12 is his redemptive answer to the scattering of nations. Pentecost in Acts 2 is its ultimate reversal.

What covenants does God establish in Genesis?

Genesis establishes the covenant of works with Adam (Genesis 2:15–17), inaugurates the covenant of grace in Genesis 3:15, ratifies the Noahic covenant (Genesis 9:8–17), and establishes the Abrahamic covenant (Genesis 12; 15; 17). Reformed covenant theology understands all these as administrations of the one covenant of grace, with Christ as their substance and fulfillment.

How does Genesis connect to the Westminster Confession of Faith?

Genesis is the exegetical bedrock of Westminster theology. Creation ex nihilo (WCF 4.1) from Genesis 1:1. The fall and original sin (WCF 6.1–3) from Genesis 3. The covenant of works (WCF 7.2) from Genesis 2:15–17. The covenant of grace (WCF 7.3) from Genesis 3:15. The Abrahamic covenant as an administration of grace (WCF 7.5) from Genesis 12, 15, and 17.

What is the redemptive-historical significance of Genesis?

Genesis begins the single story Scripture tells from creation to new creation. Every major biblical theme — image of God, covenant, sacrifice, promise, redemption — originates here. Jesus told his disciples: Beginning at Moses and all the Prophets, He expounded in all the Scriptures the things concerning Himself (Luke 24:27). That exposition began in Genesis 3:15.
