Question 1

Why did God accept Abel’s offering but not Cain’s?

Accepted Answer

The passage shows that God looked not only at the gifts, but at the men who brought them. Abel brought the firstborn of his flock and their fat, the best and most costly part, as an act of faith that admitted his sin and need for God’s mercy. God “had respect unto Abel and to his offering,” meaning Abel himself was accepted first. Cain also brought from the ground, but his heart was not right. His worship was outward without true trust or humility, so both he and his offering were rejected.

Question 2

What does it mean that "sin lieth at the door" in this story?

Accepted Answer

When God warned Cain, “If thou doest not well, sin lieth at the door,” he was telling Cain that sin was very near and ready to take over if he did not turn back. Cain’s anger and jealousy toward Abel were like a wild animal crouching at the doorway, waiting to come in. Some have also understood this wording as hinting that a way of dealing with sin was close at hand. Either way, God is saying Cain is not helpless. If he does well and turns to God, he will be accepted, and sin will not rule him.

Question 3

Why did Cain kill Abel his brother?

Accepted Answer

Cain killed Abel because he was angry and jealous that God accepted Abel and not him. Instead of checking his own heart and listening to God’s warning, Cain let his hurt pride grow into hatred. The text says he spoke with Abel and then, when they were in the field, rose up and killed him. There is no hint that Abel wronged Cain. The root was Cain’s resentment at God’s favor toward Abel. This shows how refusing to face our own sin can lead us to strike out at others, even those closest to us.

Question 4

What does Cain mean when he says, "Am I my brother's keeper?"

Accepted Answer

When God asks, “Where is Abel thy brother?” Cain answers, “I know not: Am I my brother’s keeper?” He is lying and also speaking in a hard, disrespectful way. The question is meant to dodge responsibility, as if he is saying, “It’s not my job to watch him.” In reality, he had just killed Abel. His words show the spirit of someone who has sinned, been warned, and now refuses to confess, even to God. The story makes clear that we are not free to ignore the good of our brothers and sisters, and God does hold us responsible.

Question 5

What does it mean that Abel’s blood cried to God from the ground?

Accepted Answer

God says to Cain, “The voice of thy brother’s blood crieth unto me from the ground.” Abel’s blood did not speak with human words, but the murder itself called out to God for justice. The ground had “opened her mouth” to take in Abel’s blood, and now it was like a witness against Cain. This shows that even when no person sees or reports a crime, God sees it. Wrong done to God’s people does not stay hidden. The picture of blood crying out tells us that God will answer and avenge evil in his time.

Question 6

What was Cain’s punishment and why did God still protect him?

Accepted Answer

God cursed Cain “from the earth,” so the ground would no longer yield its strength to him. The work that once gave him fruit would now fight him. God also said he would be “a fugitive and a vagabond,” restless and without a settled home, with a troubled heart. Cain felt this was more than he could bear and feared others would kill him. Yet God, while judging him, also put a mark on Cain so that no one should kill him, and warned that anyone who did would face sevenfold vengeance. This shows both God’s justice and his restraint of further violence.

Question 7

What is the mark of Cain, and what was its purpose?

Accepted Answer

The passage says, “The LORD set a mark upon Cain, lest any finding him should kill him,” but it does not describe what the mark looked like. The main point is its purpose, not its form. It was a visible sign tied to God’s word that warned others not to kill Cain. God attached a threat of sevenfold vengeance to anyone who ignored it. The mark did not remove Cain’s guilt or curse. It served to limit more bloodshed and to make Cain a sober warning to others about the cost of shedding innocent blood.

Question 8

How does this story show both God’s justice and God’s mercy?

Accepted Answer

In this passage, God’s justice appears in how he exposes Cain’s sin, hears the cry of Abel’s blood, and curses Cain’s work and wandering life. God does not accept hypocritical worship, and he does not overlook murder. At the same time, God speaks with Cain more than once, warns him about sin before the murder, and after the crime still gives him a mark of protection. Even in judgment, God slows the spread of violence and leaves space for Cain to feel his guilt and seek mercy. Justice and kindness appear side by side.

Question 9

What does this passage teach about the kind of worship God accepts today?

Accepted Answer

The story shows that God cares first about the person, then about the gift. Abel is described as bringing the firstborn and the fat, the best of his flock, in faith. Cain brings an offering, but with a heart that is not right. God tells Cain, “If thou doest well, shalt thou not be accepted?” This means God looks for a sincere heart that trusts him, admits sin, and comes on his terms, not our own. For us today, it warns against empty religious acts and calls us to come to God with honest faith, obedience, and our best, not leftovers.

Question 10

Why is the phrase "sin lieth at the door" sometimes seen as difficult to understand?

Accepted Answer

The wording about sin lying at the door is brief and can be taken in more than one way. Many understand it as a picture of sin like a wild beast ready to spring if Cain does not do well. Others see in the wording a hint that a way of dealing with sin, like a sin offering, is near at hand. What is clear in both readings is that Cain is not trapped by fate. God tells him that if he does well he will be accepted, and that he is meant to rule over what threatens him, not give in to it.
