Why does God permit Jacob's deceit?
Why does God allow Jacob's deceit in Genesis 27:20 to succeed?

The Narrative Moment: Genesis 27:20

“Isaac asked his son, ‘How did you find it so quickly, my son?’ ‘Because the LORD your God granted me success,’ he replied.”


Cultural and Historical Context

In the second millennium BC Near East, birthright and blessing determined clan leadership. Nuzi and Mari tablets attest to legally binding oral blessings and the use of disguises or substitutions to secure inheritance. While Scripture never condones the practices, the cultural backdrop explains why Jacob and Rebekah believed the window of opportunity was narrow and decisive.


Divine Sovereignty and Covenant Election

1. Prenatal Oracle – “The older will serve the younger” (Genesis 25:23). God’s sovereign choice of Jacob preceded any moral performance (Romans 9:10-13).

2. Irrevocable Promise – God had sworn to Abraham that the covenant line would continue (Genesis 22:16-18). His determination to bless Jacob cannot be thwarted by Isaac’s contrary intention to favor Esau.

3. Instrumentality of Human Actions – God frequently works through human decisions without endorsing their morality (Proverbs 16:1; Acts 2:23).


Human Responsibility and Moral Accountability

Jacob’s lie violates the ninth commandment’s principle (later codified in Exodus 20:16). Scripture candidly records the sin, and subsequent narrative justice follows:

• Jacob himself is deceived by Laban (Genesis 29:25).

• His sons deceive him with Joseph’s robe (Genesis 37:31-33).

Reaping what one sows (Galatians 6:7) demonstrates God’s commitment to moral order even while His redemptive plan advances.


Providence Through Imperfection

Genesis repeatedly shows God bending flawed human choices toward His holy ends (Genesis 50:20). Jacob’s success highlights:

• The mismatch between human merit and divine grace.

• God’s ability to write straight with crooked lines, magnifying His glory and eliminating any grounds for boasting (Ephesians 2:8-9).


Foreshadowing the Gospel

Jacob, clothed in another’s garments to receive a blessing, prefigures the believer clothed in Christ’s righteousness (Isaiah 61:10; 2 Corinthians 5:21). The episode prepares readers for the greater substitution that secures an everlasting inheritance (Hebrews 9:15).


Philosophical Clarification: Freedom and Foreordination

Scripture affirms both genuine creaturely choice and exhaustive divine foreknowledge. Jacob’s act was freely chosen, yet God’s foreordained purpose absorbed it without becoming the author of sin (James 1:13). Classical Christian theism maintains this compatibility, avoiding both fatalism and open theism.


Theological Lessons for Believers

1. God’s plan is unstoppable, yet personal holiness still matters.

2. Divine blessing is granted by grace, not by manipulation.

3. Sin has temporal consequences even when eternal purposes stand secure.

4. Trusting God’s timing is wiser than seizing outcomes by fleshly means.


Practical Application

When tempted to achieve good ends through questionable means, remember Jacob’s mixed legacy. Wait upon the Lord (Psalm 27:14). Integrity aligns us with God’s character and spares us later sorrow.


Conclusion

God allowed Jacob’s deceit to succeed because His covenant determination overruled Isaac’s misplaced preference, illustrating that His redemptive purposes operate even through human frailty. The episode exalts sovereign grace, vindicates prophetic foreknowledge, and foreshadows the gospel dynamic whereby the unworthy are blessed through substitution—ultimately fulfilled in the resurrected Christ.
