BEFORE THE JOURNEY

Editorial Preface

Genesis 4 moves the biblical story outside Eden and into the first generation born after the Fall. Sin is no longer seen only in humanity’s rebellion against God; it now reaches into the relationship between brothers. Cain and Abel stand before the LORD with offerings, Cain receives a direct warning about sin, Abel is murdered, and God confronts the murderer. This study will remain anchored in Genesis 4:1–16 while allowing later Scripture to clarify what the Bible itself later says about Abel’s faith, Cain’s works, and the blood of Jesus.

Where Genesis is explicit, we will speak explicitly. Where later inspired Scripture supplies further light, we will identify that source. Where interpreters have proposed explanations that the text itself does not state, we will mark them as interpretation rather than Scripture.

CHAPTER 1

Life Outside Eden

Genesis 4 begins after Adam and Eve have been expelled from Eden. The ground is still God’s creation, human life continues by His providence, and the command to be fruitful has not disappeared. Yet the effects of Genesis 3 now accompany the human family. The first children named in Scripture are born into a world where sin and death have entered human experience.

This setting matters. Cain’s later violence is not an isolated story disconnected from the Fall. Genesis places it immediately after humanity’s rebellion so that the reader sees sin moving outward—from distrust of God to hostility toward another human being.

CHAPTER 2

Cain and Abel Are Born

Genesis 4:1 records Eve giving birth to Cain and acknowledging the LORD in connection with the birth. Verse 2 then introduces Abel. Scripture gives us only a few details about their early lives, so faithful study must resist filling the silence with imagined history.

What Scripture does make clear is that both brothers belong to the same first human family. Their story will demonstrate that proximity, shared ancestry, and shared knowledge of God do not by themselves produce the same response of faith and obedience.

CHAPTER 3

Two Brothers, Two Vocations

Abel becomes a keeper of sheep, while Cain becomes a worker of the ground (Genesis 4:2). Genesis does not condemn either vocation. Shepherding and cultivating the earth are presented simply as their work.

This is important because the later difference between their offerings must not be reduced to the claim that one occupation was holy and the other was not. Scripture does not say that. The issue lies deeper than profession.

CHAPTER 4

The Brothers Bring Their Offerings

In the course of time Cain brings an offering from the fruit of the ground, and Abel brings from the firstborn of his flock and their fat portions (Genesis 4:3–4). Both brothers approach the LORD with offerings.

Genesis describes Abel’s gift with particularity—firstborn and fat portions—while Cain’s is described more generally. These textual details are worth observing, but observation must not become speculation. Genesis does not provide a previously recorded command in this passage requiring an animal sacrifice from these brothers.

CHAPTER 5

The LORD Regards Abel and His Offering

Genesis 4:4–5 says that the LORD had regard for Abel and his offering, but for Cain and his offering He had no regard. Notice the order: the text speaks of the person and the offering together.

The passage does not invite us to treat worship as a mechanical transaction in which the correct object forces divine acceptance. God sees the worshiper as well as the gift. Later Scripture will provide further inspired commentary on the contrast between the brothers.

CHAPTER 6

Why Was Abel’s Offering Accepted?

Genesis itself does not give a single sentence saying, “Abel was accepted because…” Therefore we should not pretend that a popular explanation is written directly into Genesis 4.

Hebrews 11:4 does give inspired clarification: “By faith Abel offered unto God a more excellent sacrifice than Cain.” The New Testament therefore places faith at the center of Abel’s offering. First John 3:12 adds that Cain’s works were evil and his brother’s righteous. These later texts illuminate Genesis without requiring us to invent an unstated rule about the material of the offerings.

CHAPTER 7

Cain’s Anger and Fallen Countenance

Cain responds to God’s lack of regard with great anger, and his face falls (Genesis 4:5). The rejection exposes what is happening within him.

At this point Cain has not yet murdered Abel. The narrative pauses before the violence. That pause is crucial because God addresses Cain while there is still an opportunity to respond differently.

CHAPTER 8

God Comes to Cain

The LORD asks Cain, “Why are you angry?” and “Why has your face fallen?” (Genesis 4:6). God’s questions are not evidence of ignorance. As elsewhere in Genesis, divine questioning brings the human person face to face with moral reality.

Before judgment falls for murder, Cain receives words from God. The Creator does not leave him without warning.

CHAPTER 9

“If You Do Well”

Genesis 4:7 places responsibility before Cain: “If you do well, will you not be accepted?” The verse refuses the idea that Cain is trapped by resentment with no meaningful responsibility for his response.

God’s words direct Cain away from blaming Abel and toward his own conduct. The central question is not what Abel possesses, but whether Cain will heed God.

CHAPTER 10

“Sin Is Crouching at the Door”

God warns Cain that sin is crouching at the door and that its desire is for him, but he must rule over it (Genesis 4:7). The imagery makes sin appear near, active, and threatening.

The warning comes before the murder. Scripture therefore shows both the seriousness of sin and Cain’s accountability. Sin seeks mastery; Cain is commanded not to surrender to it.

CHAPTER 11

Cain Rejects God’s Warning

Genesis moves from God’s warning to Cain and Abel in the field. Whatever details surrounded the encounter, the decisive fact is explicit: Cain rises against Abel his brother and kills him (Genesis 4:8).

The repeated word “brother” intensifies the horror. The one Cain attacks is not a stranger or enemy. Sin has now ruptured the most intimate human bond outside marriage.

CHAPTER 12

The First Murder

Abel’s death is the first human killing recorded in Scripture. Death, warned about in Eden, is now inflicted by one image-bearer upon another.

First John 3:12 later warns believers not to be like Cain, “who was of that wicked one, and slew his brother.” John connects the murder with Cain’s evil works and Abel’s righteous works. Hatred of righteousness becomes violence against the righteous brother.

CHAPTER 13

“Where Is Abel Your Brother?”

The LORD asks Cain, “Where is Abel thy brother?” (Genesis 4:9). The question recalls God’s approach to Adam after the Fall: the sinner is summoned to answer before God.

Cain replies that he does not know. The lie compounds the violence. Sin against a brother is followed by falsehood before God.

CHAPTER 14

“Am I My Brother’s Keeper?”

Cain’s question—“Am I my brother’s keeper?”—attempts to distance himself from responsibility. Yet the narrative has already answered morally: Cain was certainly not entitled to destroy his brother.

Scripture does not use this verse to establish every possible social obligation, but it unmistakably exposes Cain’s refusal to acknowledge responsibility after taking Abel’s life.

CHAPTER 15

Abel’s Blood Cries From the Ground

God declares that the voice of Abel’s blood cries to Him from the ground (Genesis 4:10). The murder may have occurred away from other human witnesses, but it is not hidden from God.

The ground that received Abel’s blood becomes a witness within the judgment scene. Innocent blood calls for justice before the righteous Judge.

CHAPTER 16

God Judges Cain

Cain is cursed from the ground, which will no longer yield its strength to him, and he will be a fugitive and wanderer on the earth (Genesis 4:11–12). His vocation as a worker of the ground is directly affected by the judgment.

Cain fears the consequences and the possibility that someone who finds him will kill him. Judgment is real, personal, and connected to the evil he has done.

CHAPTER 17

The Mark of Cain and God’s Restraint

The LORD declares that vengeance against Cain will be answered sevenfold and places a mark on Cain so that whoever finds him will not kill him (Genesis 4:15). Scripture does not tell us what the mark physically looked like.

We should therefore reject attempts to identify the mark with a race, skin color, ethnicity, or any other feature the Bible never names. The text presents the mark as protection from retaliatory killing. Even while judging Cain, God restrains further vengeance.

CHAPTER 18

From Abel’s Blood to the Blood of Jesus

Genesis 4 ends this section with Cain going out from the presence of the LORD and dwelling in the land of Nod, east of Eden (Genesis 4:16). The movement away from Eden continues.

Yet Abel is not forgotten in the rest of Scripture. Jesus calls him “righteous Abel” (Matthew 23:35). Hebrews 11:4 presents his offering as an act of faith. Most strikingly, Hebrews 12:24 speaks of Jesus, the mediator of the new covenant, and “the blood of sprinkling, that speaketh better things than that of Abel.” This connection is not an imposed symbolism; Hebrews itself makes the comparison.

Abel’s blood cries from the ground in the context of murder and justice. The blood of Jesus stands at the center of the new covenant and redemption. The canonical movement therefore carries us from the first murdered righteous man to the righteous Son whose sacrificial blood accomplishes what Abel’s could not.
