What are the "two unchangeable things" mentioned in Hebrews 6:18? Introductory Statement Of The Passage “17 In the same way God, when He wanted to make the unchanging nature of His purpose very clear to the heirs of the promise, confirmed it with an oath. 18 So that by two unchangeable things, in which it is impossible for God to lie, we who have fled to take hold of the hope set before us may be strongly encouraged.” The question: What precisely are the “two unchangeable things” (δύο πραγμάτων ἀμεταθετήτων)? Scripture identifies them within the wider argument: (1) God’s PROMISE, and (2) God’s OATH. Literary And Historical Context Hebrews addresses Jewish believers tempted to abandon Christ. The author cites God’s dealings with Abraham (Genesis 22) where the patriarch received both a promise (“I will surely bless you,” Genesis 22:17) and an oath (“By Myself I have sworn,” Genesis 22:16). The inspired writer applies that pattern to all “heirs of the promise” (Hebrews 6:17), anchoring their assurance in God’s immutable character. First Unchangeable Thing: God’S Promise • Nature of Promise: A unilateral declaration issued by the sovereign Creator (cf. Numbers 23:19). • Biblical Examples: – Promise of a Seed (Genesis 3:15). – Covenant with Abraham (Genesis 12:2-3; 15:5-6). – Davidic covenant (2 Samuel 7:12-16). – New Covenant fulfilled in Christ (Jeremiah 31:31-34; Luke 22:20). • Apostolic Confirmation: “For no matter how many promises God has made, they are ‘Yes’ in Christ” (2 Corinthians 1:20). • Unbreakable Status: “Heaven and earth may pass away, but My words will never pass away” (Matthew 24:35). Second Unchangeable Thing: God’S Oath • Definition: A sworn self-attestation in which God “swears by Himself” because “He could swear by no one greater” (Hebrews 6:13). • Old Testament Instances: – Genesis 22:16-17 (“By Myself I have sworn”). – Psalm 110:4 (“The LORD has sworn and will not change His mind, ‘You are a priest forever’”). • Purpose: To provide “superabundant” (περισσότερον) assurance (Hebrews 6:17) to Abraham and, by extension, to believers. • Irrevocability: Linked to God’s own being; He would sooner cease to exist than break His oath (cf. Isaiah 45:23; Jeremiah 22:5). The Divine Impossibility Of Lying The two certitudes are undergirded by a third, qualifying clause: “in which it is impossible for God to lie.” • Ontological Grounding: God’s holy nature (Leviticus 11:44; 1 John 1:5). • Logical Coherence: An omnipotent Being cannot act against His own essence (Titus 1:2). • Manuscript Witness: Every extant Greek text family (𝔓46, ℵ, A, B) reads ἀψεύδος θεός (“God who does not lie,” Titus 1:2), underscoring universal scribal recognition of this attribute. Harmony With The Abrahamic Narrative • Genesis 15: Promise ratified by covenant ritual. • Genesis 22: Oath added after the near-sacrifice of Isaac, giving double certainty. • Archaeological Note: Second-millennium B.C. suzerain-vassal treaties (e.g., Hittite texts from Boghazkoy) parallel the biblical covenant-plus-oath structure, lending historical plausibility. Christological Fulfillment • Hebrews 6:19-20 links the promise-oath pair to Christ, our “forerunner” entering the heavenly sanctuary. • Resurrection Verification: The empty tomb (Matthew 28; John 20) and post-mortem appearances (1 Corinthians 15:3-8) serve as empirical anchors that God has kept His sworn word of redemption (Acts 2:29-32). Theological Implications a. Immutability (Malachi 3:6). b. Assurance of Salvation: Eternal security rests not in human performance but in God’s double guarantee (John 10:28-29). c. Hope as “Anchor of the Soul” (Hebrews 6:19): A metaphor drawn from first-century nautical practice confirmed by Mediterranean shipwreck excavations (e.g., the Alexandrian grain ship’s anchor weights recovered off Malta, Acts 27). Pastoral And Practical Application • Encouragement for the Persecuted: Believers “flee” (φεύγοντες) to this refuge, echoing Asylum-City imagery (Numbers 35). • Ethical Outflow: Because God keeps His word, Christian speech must mirror His truthfulness (Ephesians 4:25). • Evangelistic Invitation: All humanity is called to entrust themselves to the unbreakable promise-oath of God in Christ (Romans 10:9-13). Conclusion The “two unchangeable things” of Hebrews 6:18 are God’s PROMISE and God’s OATH. Rooted in His flawless character and validated in the resurrected Christ, they guarantee salvation to all who take refuge in Him, providing an unshakable foundation for faith, life, and hope. |
