III. The Fairness and Purpose of Imputed Sin

Key Question:“How is it fair that Adam’s sin is imputed to all humanity?”



Doctrinal Principle:Imputation of Adam’s sin is a grace act, qualifying all for salvation.




IV. Scriptural Foundation for Universal Condemnation and Grace

Romans 11:32“For God has shut up all in disobedience so that He may show mercy to all.”

Exegetical Note: Universal condemnation precedes universal offer of mercy.

V. The Age of Accountability and Divine Justice

Principle:Children dying before accountability are saved by God’s justice.



Doctrine:God’s justice cannot condemn without opportunity for faith in Christ.




VI. The Justice and Righteousness of God

Essence of God:God is perfectly just and righteous; cannot overlook sin.

Exegetical Note: Propitiation—Christ’s work satisfies God’s justice.



Illustration:Adam and Eve’s sins: Adam sinned knowingly (disobedience), Eve wasdeceived.




VII. The Transmission of Sin and Spiritual Death

Doctrine:Adam’s original sin is imputed at birth; the old sin nature is transmittedgenetically.



Genesis Reference:“You shall surely die”—spiritual death, not immediate physical death.



Adam’s State Post-Fall:Lost spirit (fellowship), gained old sin nature and imputed sin.




VIII. God’s Role in Sin and Creation

Principle:God is not the author of sin; Adam is.

Exegetical Note: The soul is created perfect, corrupted only by the old sinnature.



Angelic Conflict:Satan as the first sinner; Adam responsible for human fall.




IX. Federal Headship and Imputation

Doctrine:Adam as federal head; his sin imputed to all humanity.



Scripture Reference:1 Corinthians 15:21-22 (NLT)“Death came into the world through a man… resurrection through anotherman.”



Exegetical Note: Adam’s sin brings death; Christ brings life.




X. Distinction Between Adam’s and Eve’s Sin

Scripture Reference:1 Timothy 2:13-14“Adam was not deceived, but the woman being deceived…”



Exegetical Note: Adam’s volitional disobedience is the basis for imputation.




XI. The Law, Sin, and Grace

Scripture Reference:Romans 5:12-17 (NLT)Sin entered through Adam; grace and forgiveness through Christ.



Exegetical Note: Sin existed before the Mosaic Law; law made sin explicit.




XII. The Work of Christ: Propitiation and ImputedRighteousness

Doctrine:Christ’s righteousness imputed to believers; God sees Christ, not our sin.

Illustration: Courtroom analogy—Jesus as our advocate and substitute.




XIII. The Nature of Christ’s Humanity

Doctrine:Jesus: 100% God, 100% man; no inherited sin nature due to virgin birth.

Exegetical Note: No transmission of sin via sexual intercourse/DNA.




XIV. The Believer’s New Position

Doctrine:Believers possess body, soul, and restored spirit (Holy Spirit indwelling).

Adam’s original sin forgiven; old sin nature remains until physical death.

Principle: The struggle between flesh and spirit (Galatians 5:17 implied).




XV. The Importance of Doctrinal Understanding

Application:Knowing the doctrine equips believers to resist the old sin nature.

Repetition and vocabulary deepen understanding and recall.




XVI. The Superiority of the Believer’s Position

Doctrine:Believers are priests and ambassadors; possess privileges Adam did not.

Illustration: Old Testament priests vs. Church Age believers.




XVII. Examples of Biblical Heroes and the Old SinNature

Principle:Even great biblical figures fell to the old sin nature.

Daily choice: walk by the Spirit or by the flesh.




XVIII. Adoption and Sonship

Scripture Reference:Romans 8:14-18 (NLT)Led by the Spirit; adopted as sons and daughters; heirs with Christ.



Exegetical Note: “Abba Father”—unique privilege of Church Age believers.

Principle: Suffering now, future glory promised.




XIX. The Hope and Security of the Believer

Scripture Reference:Romans 8:28-30 (NLT)God works all things for good; foreknowledge and predestination explained.



Exegetical Note: Free will affirmed; God’s foreknowledge, not coercion.




XX. Responsibilities of Sonship

Doctrine:Freedom from bondage; confidence and security in relationship with God.

Privileges: sonship, inheritance, royal priesthood.

Responsibilities: reflect God’s likeness, love others, operate in royal familyhonor code.




XXI. The Old Sin Nature as a Reminder

Scripture Reference:Romans 7 (implied)Paul’s struggle with sin; old sin nature reminds us of our need for Christ.






XXII. The Covering of Sin: Fig Leaves vs. Animal Skins

Genesis Reference:Adam and Eve’s attempt to cover with leaves; God provides animal skins.

Exegetical Note: Animal sacrifice foreshadows Christ’s atonement; humansolutions insufficient.
