How is Jesus unchanging despite changes?
(Hebrews 13:8) If Jesus is unchanging “yesterday and today and forever,” how do we reconcile His birth, death, and resurrection as actual changes?

Understanding the Unchanging Nature of Jesus

Hebrews 13:8 states: “Jesus Christ is the same yesterday and today and forever.” This statement raises the question: How can Jesus be unchanging if He was born, died, and rose again—seemingly undergoing changes in status and condition? The discussion that follows is intended to address this by examining scriptural teaching, theological context, and additional considerations that underscore the continuity of His divine nature, even as He experienced real events in human history.


1. The Scriptural Assertion of Christ’s Immutability

Hebrews 13:8 in Context

The phrase “Jesus Christ is the same yesterday and today and forever” comes in the midst of encouragements for believers to hold firmly to faith without being carried away by strange teachings (Hebrews 13:9). Thus, the writer underscores that, unlike earthly traditions and leaders who come and go, the Lord remains constant in His divine nature and character.

Other Scriptural Witnesses

Malachi 3:6 records a parallel divine claim: “I, the LORD, do not change.”

John 1:1 describes Jesus (the Word) as co-eternal with God, stating, “In the beginning was the Word, and the Word was with God, and the Word was God.”

John 10:30 quotes Jesus: “I and the Father are one.”

Taken together, these passages confirm that any discussion of Jesus’ “changes” must not override the fundamental truth of His eternal and unchanging divine essence.


2. The Incarnation: Addition, Not Alteration of Divine Nature

Concept of “Taking On” Human Form

John 1:14 declares, “The Word became flesh and made His dwelling among us.” Instead of ceasing to be God or transforming from one nature into another, the eternal Son added a genuine human nature to His immutable divinity at the Incarnation. This addition of a human nature did not diminish His deity. Philippians 2:7–8 highlights that He “emptied Himself, taking the form of a servant, being made in human likeness. And being found in appearance as a man, He humbled Himself and became obedient to death—even death on a cross.”

Hypostatic Union

Christian teaching describes the union of Jesus’ fully divine and fully human natures—two distinct natures united in one Person—often called the “Hypostatic Union.” This union explains how Jesus could experience birth, physical growth (Luke 2:52), suffering, and death in His humanity, while His divine essence remained unaltered and eternally consistent.


3. Birth, Death, and Resurrection as Historical Events

Entering Time Without Losing Eternity

By being born of a virgin (Matthew 1:23) in a specific place and time, Jesus entered human history. Such an event represents a momentous occurrence in the human timeline. Yet it does not denote a fundamental shift in His eternal being. Rather, it testifies to His willingness to step into time and space for the sake of humanity’s redemption.

Real Death, Real Resurrection

Scripture (1 Corinthians 15:3–4) affirms that Jesus truly died: “Christ died for our sins… He was buried, He was raised on the third day.” The fact that He physically died on the cross pertains to His genuine human nature. Meanwhile, the divine Son remained who He was, even as His human body lay in the tomb. The resurrection celebrates His triumph over death, uniting body and spirit once more in a glorified form.

Luke 24 and John 20–21 record multiple post-resurrection appearances, providing firsthand and eyewitness testimony. Early manuscript evidence (such as Papyrus 66, Papyrus 75, Codex Sinaiticus) further supports the scriptural assertion that the events surrounding Jesus’ death and resurrection were well-preserved, historically robust, and widely attested. Archaeological findings in and around Jerusalem (including the recognized traditional site of Golgotha) support the biblical descriptions of locations where these events transpired.


4. Divine Nature vs. Human Experience

Eternal Consistency of Character

Jesus displayed consistent attributes such as truth (John 14:6), righteousness (Acts 7:52), and love (Romans 5:8). At no point—birth, ministry, death, or resurrection—did He compromise or relinquish His divine moral perfections. In this sense, He remains the same in character, purpose, and divine identity across all stages of earthly life and beyond.

Changing Roles Without Changing Essence

• As Creator (John 1:3), He was eternally involved in making all things.

• As Redeemer, He stepped into history to save (Mark 10:45).

• As High Priest, He intercedes (Hebrews 7:24–25).

These roles clarify different aspects of His work but do not alter His eternal deity. He is “the same” in being and essence, though He accomplishes distinct redemptive tasks within time.


5. Philosophical and Theological Consistency

Immutability in Eternity

From a philosophical standpoint, God’s immutability refers to the unchanging nature of His being, not to the impossibility of God acting within time. The addition of human nature in the Incarnation is God’s free action, not a modification of His eternal attributes.

Behavioral and Existential Encounter

Human language often describes “changes” from our perspective because we see events unfold over time. Yet from the standpoint of an eternal Creator, the plan of salvation, including the Incarnation and Resurrection, stands consistent with His unchanging purpose: to reconcile a fallen world to Himself (Ephesians 1:4–10).


6. The Testimony of Manuscripts and History

Preservation of the Record

The New Testament writings, through thousands of Greek manuscripts, Latin translations, and quotations from early Church Fathers, present a coherent message that Jesus is one with the Father and has an unchanging divine nature. Such manuscript evidence underscores that the early church, from the very beginning, understood Him as divine and eternally constant.

Corroboration from Ancient Writings

Early non-Christian sources (e.g., Jewish historian Josephus) and later Roman historians refer to Jesus’ crucifixion under Pontius Pilate, lending credibility to the reliability of these events. The consistent biblical text aligns with these external testimonies, revealing no contradictory shift in describing His deity. Instead, the uniform witness is that He is God incarnate, fulfilling a set purpose through actual historical events.


7. Reconciling the Seeming Paradox

To answer directly: The birth, death, and resurrection describe changes in Christ’s human experience, not alterations to His divine nature. He remains the same Lord of eternity, simultaneously choosing to experience human life fully. These events mark distinct milestones in the timeline of history, yet He stands unchanged in His essence. Hebrews 13:8 therefore remains true: "Jesus Christ is the same yesterday and today and forever."


8. Conclusion

Jesus' immutability affirms that no external factors or internal alterations can affect His divine nature. The Incarnation, crucifixion, and resurrection represent His engagement in real historical events for the sake of humanity’s redemption—an act of love and mercy consistent with the character He has always possessed.

Far from contradicting Hebrews 13:8, Christ’s earthly life and resurrection confirm His steadfast essence and eternal mission. In every stage of His redemptive work, He demonstrates the same ultimate purpose and love. Thus, what appears to us as “change” is, in fact, the outworking of God’s unchanging plan for salvation, manifested by the One whose divine nature remains the same across all eternity.
