ACTS BIBLE
Creation week 4 · Genesis 4; Hebrews 11; Job 40-41; Romans 1-2
Cain did not repent, and Cain's line became depraved. Faith and unbelief start branching here.
The gate to Eden has just been shut behind them, and a man kills his brother over worship. That is how fast it moves.
Genesis 4 does two things at once. It tells you what happened to one family, and it starts two family trees that run in opposite directions for the rest of the book. Everything after this is one of those two lines.
This week goes to Job 40 and 41, where God describes two creatures called Behemoth and Leviathan. Open almost any study Bible and the footnote will tell you Behemoth is a hippopotamus and Leviathan is a crocodile.1 That is the mainstream reading, it is in the margins of Bibles good men translated, and waving it away would be dishonest.
So take it seriously and then read what the text actually says.
God says Behemoth "stiffens his tail like a cedar."2 A hippopotamus has a tail roughly the size of your forearm. Whatever else is true, that clause does not describe one. Of Leviathan God says no sword or spear can touch him, that his back is rows of shields sealed so tight no air passes between, and that firebrands come out of his mouth.3 Crocodiles are hunted with spears and always have been.
Here is the honest shape of it. The text does not say dinosaur, and the word did not exist until Richard Owen coined it in 1841 out of the Greek for terrible lizard.4 Reading one in is an inference, and it should be offered as an inference. But the descriptions do not fit the animals the footnotes name either, and the reason the footnotes name them is that those are the largest creatures anyone knew of when the notes were written. Both sides are guessing. Only one side admits it.
Cain brings some of the produce of the ground. Abel brings the firstborn of his flock, and their fat portions.5 God looks with favour on Abel and his offering, and not on Cain and his.
The text does not say why, and people have argued about it for a long time. Grain versus blood is the usual answer, and it may be part of it. But look at the order of the words: God had regard for Abel and his offering. The man before the gift.
Hebrews settles it. By faith Abel offered a better sacrifice than Cain.6 The difference was not the produce. It was faith, and Genesis leaves that for the New Testament to say out loud. That is worth noticing as a method: Scripture explains Scripture, and the Bible's own commentary beats ours.
This is the hinge of the chapter, and it is where the whole week turns.
God does not strike Cain down when his face falls. He comes and talks to him. Why are you angry? If you do what is right, will you not be accepted? And then the warning: sin is crouching at the door, its desire is for you, but you must rule over it.7
Cain gets a conversation, a diagnosis and a way out before he ever lifts his hand. He goes and does it anyway. And afterward, asked where his brother is, he lies and then sneers.8 There is no sorrow in the chapter. He grieves the punishment and never the act.
That is what makes this a fork rather than an incident.
Read the two genealogies side by side and the chapter tells you what it is doing.
Cain's line runs Enoch, Irad, Mehujael, Methushael, Lamech. It builds a city, and it produces the first herdsmen, the first musicians, and the first metalworkers in bronze and iron.9 Real culture, real skill, real achievement. Nothing in the text sneers at any of it.
And it ends with Lamech standing in front of his two wives making a song out of killing a man, and boasting that if Cain is avenged seven times, he will be avenged seventy-seven.10 Five generations from the first murder, murder is a thing you write music about.
Seth's line gets one sentence in this chapter, and it is the whole counterweight: at that time people began to call on the name of the LORD.11
Two lines, both making things. One builds and boasts. One builds and prays.
Follow Cain's line two chapters further and Genesis renders the verdict: the LORD saw that human wickedness was widespread, and that every inclination of the human heart was nothing but evil all the time.12 That is where this trajectory arrives, and it is the reason the flood is in the book. Jeremiah says the same thing about the same organ centuries later, that the heart is more deceitful than anything else.13 The diagnosis does not change between Genesis and Jeremiah, and it has not changed since. The man in the pew today carries the identical heart Cain was warned about, which is why the warning still reads as current rather than ancient.
God spends two chapters at the end of Job describing animals, and it is not a nature lesson. Job has demanded an audience. God gives him one and spends it on creatures.
The point of Behemoth and Leviathan is not zoology, it is scale. God is saying, look at what I made and cannot be mastered by you. If you cannot put a hook in this one's nose, on what basis are you cross-examining me?14
Whatever those animals were, they were real to Job and real to whoever first read the book. God does not build an argument on a myth.
The King James translates a Hebrew word as dragon thirty-five times, twenty-two in the Old Testament and thirteen in the New, and every one of the thirteen is in Revelation.15
Two things need saying about that.
The Hebrew behind most of the Old Testament ones is tannin, and modern translations render it jackal, serpent or sea monster depending on the sentence.16 So the count is a fact about the King James, not a fact about Hebrew. Better to say that ourselves than to have it said back to us.
What is harder to wave off is the written record outside Scripture. Large reptilian creatures show up in serious accounts across unrelated cultures, and not only in myth: Herodotus describes winged serpents in Egypt, and Ulisse Aldrovandi, a founder of natural history, catalogued one in the sixteenth century.17 People who had no contact with each other described the same kind of animal. That is either a coincidence repeated worldwide or a memory.
Paul says what can be known about God is plain, because God has shown it, and that his invisible attributes have been clearly seen since the creation of the world in the things that were made. Therefore they are without excuse.18
Then the mechanism: they did not honour him, their thinking became futile, and claiming to be wise they became fools. They exchanged the truth about God for a lie and worshipped created things rather than the Creator.19
Notice that is not a description of ignorance. It is a description of exchange, which is a decision. Romans 1 does not say the evidence is unavailable. It says the evidence is refused.
The Bible is our final authority. Genesis 4 never tells us why Abel's offering was accepted. Hebrews 11 does. We did not solve it with a theory about grain and blood; we let a later part of Scripture explain an earlier one. That is the discipline, and it is the same one that keeps us from reading our own century into Job 40.
Christ's work is finished. Abel's blood cries out from the ground for justice. Hebrews says we have come to the sprinkled blood that speaks a better word than the blood of Abel.20 Abel's blood demanded; Christ's blood answers. One asks for payment, the other is payment, and there is nothing left for us to add.
God chooses. He had regard for Abel and his offering, in that order. And he goes to Cain before the murder, unasked, with a warning nobody had earned. Even the mark he puts on Cain afterward is protection rather than punishment.21
Salvation is God's work from start to finish. Everything good in this chapter is God moving first: the warning to Cain, the regard for Abel, the mark, and the line through Seth that begins to call on his name. Nobody in Genesis 4 works their way anywhere.
Two lines start here and they never merge. One is capable, cultured, and increasingly proud of its own violence. The other calls on a name it did not invent.
You are in one of them, and it is not decided by ability. Cain's line made the music and the metal. What Seth's line had was a habit of calling on God.
Christ is the answer to the chapter in the plainest way. Abel died because he was righteous, at the hand of his brother, and his blood cried out. Christ died because he was righteous, at the hands of his brothers, and lived the obedient life Cain refused before he did. Then his blood spoke, and what it said was not vengeance.
Next week: Genesis 5 is the chapter people skip. Ten names and a column of numbers, and read out loud it is the sound of chapter 3's sentence being carried out one man at a time.
Genesis 4:7. If you do what is right, will you not be accepted? But if you do not do what is right, sin is crouching at the door. Its desire is for you, but you must rule over it.
That was said to a man before he did the worst thing he ever did. The warning came in time. It usually does.
add that Genesis leaves out, and why do you think Genesis left it?
how God deals with people who are already angry?
fact that the text credits them plainly?
in the class insisted it is a hippopotamus?
someone trade something they knew?
