The Enigma of Onan: Understanding God’s Judgment on Rebellion and A Corrupt Heart ✨
The biblical narrative contains some moments that are so jarring, they challenge our modern sensibilities and force us to confront the absolute holiness of God. One of the most shocking and controversial of these stories is found in Genesis, where God strikes a man dead for a seemingly private act. God killed a man… because he wouldn’t sleep with his wife.
But the story of Onan, in Genesis 38, is not what it seems. It is not a story about sex, but about a man’s willful rebellion, his profound disrespect for a sacred covenant, and the corrupt desires of his heart. This article will delve into this ancient, mysterious account, exploring the context of the law of levirate marriage, the true nature of Onan’s sin, and why God’s judgment was a righteous and necessary act. We will uncover the profound biblical truth that God did not act because of the physical act itself, but because Onan’s heart was defiant, and he openly rejected a divine command.
The Context: A Sacred Duty to Preserve a Family Line 📜
To understand the severity of God’s judgment on Onan, we must first understand the ancient law that framed his actions: the law of levirate marriage.
The Law of Levirate Marriage 👨👩👧👦
“If brothers dwell together, and one of them dies and has no son, the wife of the dead man shall not be married outside the family to a stranger. Her husband’s brother shall go in to her and take her as his wife and perform the duty of a husband’s brother to her.” — Deuteronomy 25:5 (ESV)
The purpose of this ancient law was to preserve the family line and the inheritance of a deceased brother. The first son born from this union would be legally considered the child of the deceased brother, ensuring his name and legacy would not be “blotted out of Israel” (Deuteronomy 25:6 KJV).
Judah’s Command to Onan 🗣️
In Genesis 38, this law becomes a direct command from Judah, the father of Onan, to his son. After his brother Er dies, Judah commands Onan to marry Er’s widow, Tamar:
And Judah said unto Onan, Go in unto thy brother’s wife, and marry her, and raise up seed to thy brother. — Genesis 38:8 (KJV)
The duty was clear. Onan was to take Tamar as his wife and raise up children to his deceased brother, fulfilling a sacred and divine command to preserve the family line.
Onan’s Wilful Rebellion: A Corrupt Heart and Intent 💔
Onan agreed to the duty, taking Tamar as his wife. But he had no intention of fulfilling his sacred responsibility. His heart was filled with profound selfishness, and his actions were a blatant act of rebellion against the divine command.
The Betrayal of a Sacred Covenant 🐍
Onan’s sin was a betrayal of a sacred covenant. He wanted the pleasure of the marriage but rejected the responsibility that came with it. His obedience was partial and deceitful, a hypocritical act that God saw through. His sin was not just in the physical act itself, but in his conscious and willful refusal to honor a promise made before God.
The Sin of Intent: Rebellion and Defiance 😤
The heart of Onan’s sin was not the act itself, but the intentional, defiant rebellion against a divine command and the contempt he held for the covenant he had entered into. He had no desire to fulfill his duty to his brother or to God. His actions were a blatant act of rebellion, rooted in a corrupt heart.
God’s Judgment: The Sin Was Evil in His Sight ⚖️
And the thing which he did displeased the LORD: wherefore he slew him also. — Genesis 38:10 (KJV)
Onan’s actions were not a matter of confusion or accident; they were “evil in the sight of the LORD” because they were a direct, willful act of rebellion against a divine command. God’s judgment was a righteous response to a heart filled with profound selfishness and contempt for His will.
Why God Struck Him Down: A Judgment Against Rebellion ⚡
To our modern sensibilities, God’s judgment on Onan can seem harsh. But to understand it, we must see it not as a judgment against a specific act, but as a judgment against a willful, intentional rebellion against a holy and just God.
God’s Holiness and Justice 🔥
God’s holiness cannot tolerate such blatant, willful disobedience to a covenant. Onan’s actions were a direct affront to God’s moral law and the sanctity of the family line, which was a core part of God’s redemptive plan. God’s judgment was a righteous response to a heart filled with profound selfishness and rebellion. For more on God’s judgment, see “What Happened to Uzzah in the Bible? Why God Struck Him Dead.”
A Sinner in God’s Sight ⚖️
Onan’s sin was not a minor transgression but a profound act of defiance. He deliberately and intentionally rejected a divine command, choosing his own selfish desires over obedience to God. His actions were “evil in the sight of the LORD,” and God, as a righteous judge, had to act. This was a clear object lesson about the seriousness of the law and the sanctity of obedience to God’s commands.
A Warning to Israel 🙏
This event served as a sober warning to Israel that God takes His covenants and commands seriously. His judgment on Onan was a powerful reminder that obedience to God is not a suggestion but a sacred obligation, and that willful disobedience has severe consequences.

Theological Lessons for Believers Today 🌟
The story of Onan, while ancient and challenging, offers timeless and profound lessons for believers today.
The Heart Matters to God ❤️
God sees our intentions and our hearts. Onan’s obedience was a facade, a hollow act of selfish desire. God’s judgment was a response to the wickedness of his heart, not just the physical act itself. This reminds us that God is concerned with our inner motives as much as our outward actions.
Partial Obedience Is Disobedience 🚫
Onan’s story is a powerful reminder that partial obedience is a form of total rebellion. He obeyed by marrying his brother’s wife, but he disobeyed by refusing to fulfill the core purpose of the marriage. Our obedience to God must be complete and from a sincere heart.
God’s Promises and Covenants Are Sacred 💍
God’s covenants and commands are not to be trifled with. Onan’s contempt for the levirate law was a violation of a sacred covenant that God had established. This reminds us that God’s promises and covenants are to be taken seriously and honored with our whole heart.
God’s Sovereign Plan Prevails 🏆
Despite Onan’s rebellion, God’s sovereign plan to preserve a family line and bring about His redemptive purposes was not thwarted. God raised up another son through Judah and Tamar, ensuring His promise would be fulfilled. This reminds us that God is in complete control, and no rebellion can thwart His ultimate plan.
Conclusion: Responsibility Over Rebellion 🌍
Why did God kill a man for refusing to sleep with his wife? The answer is that God did not kill Onan for a simple act, but for his willful, intentional rebellion against a divine command and for his profound contempt for a sacred covenant. Onan wanted the pleasure of the marriage but refused the spiritual and social responsibility that came with it. His disobedience was not just a transgression of the law but an act of profound selfishness and rebellion.
God’s judgment on Onan was a righteous response to a corrupt heart and a willful rebellion. The story is a powerful reminder that God sees our hearts and our intentions, and that obedience to His commands is not a suggestion but a sacred obligation. It is a timeless lesson that we must choose responsibility over rebellion and that a sincere heart is what matters most to God.
