Why is the inheritance in Galatians 3:18 not based on the law? Text of the Verse “For if the inheritance depends on the law, it no longer depends on a promise; but God granted it to Abraham by a promise.” — Galatians 3:18 Key Vocabulary • Inheritance (κληρονομία, klēronomía): a freely bestowed possession that passes from a benefactor to an heir. • Law (νόμος, nómos): in this context, the Mosaic covenant given at Sinai, containing moral, civil, and ceremonial directives. • Promise (ἐπαγγελία, epangelía): a unilateral, gracious commitment issued by God, irreversibly grounded in His character. Historical Frame: Two Covenants, Two Natures The promise to Abraham (Genesis 12:3; 15:5-6; 22:16-18) predates the Mosaic law by “four-hundred and thirty years” (Galatians 3:17). Ancient Near-Eastern suzerainty treaties confirm that later covenants could not annul earlier grant covenants; archaeological parallels (e.g., the Lipit-Ishtar grants, c. 1900 BC) reinforce Paul’s legal logic: a grant once sealed remains inviolable. God’s covenant with Abraham functions precisely as such a grant. Chronological Priority and Irrevocability Paul’s argument is juridical: if a later stipulatory covenant (Sinai) could overturn an earlier unconditional grant (Abrahamic), the earlier covenant was never unconditional. Scripture rules that out (Genesis 15:17-18—the LORD alone passes between the pieces). To shift the inheritance to law-keeping would contradict the divine oath (Hebrews 6:13-18). Nature of the Parties: Grace vs. Performance In a grant covenant, the benefactor bears full responsibility; the recipient simply trusts. In a stipulatory (law) covenant, both parties carry obligations. Because salvation is “not by works, so that no one can boast” (Ephesians 2:8-9), it must align with the grant model. Paul therefore insists that the inheritance flows along the line of promise, unmarred by human merit (Romans 4:1-5). Purpose of the Law: Temporary Custodian, Not Life-Giver Galatians 3:19-25 identifies the law as a παιδαγωγός (“guardian”): it diagnoses sin (Romans 3:19-20), confines transgression (1 Timothy 1:8-11), and points to Christ. Once faith in the crucified-risen Messiah is revealed, the guardian’s tutoring role ends. Dependence on the tutor for inheritance is illogical; its purpose was preparatory, not salvific. Faith as the Channel of Reception Abraham “believed God, and it was credited to him as righteousness” (Genesis 15:6; Galatians 3:6). Faith, not performance, aligns the heir with the benefactor’s promise. Thus believers in Christ are “heirs according to the promise” (Galatians 3:29), sharing the same righteousness credited to Abraham (Romans 4:22-24). Cohesion of Scripture • Numbers 23:19—God does not renege on promises. • Psalm 105:8-11—He remembers His covenant with Abraham forever. • Isaiah 55:3—The “everlasting covenant” is grounded in faithful love, not law observance. • Hebrews 8:6-13—The new covenant, established on better promises, replaces the obsolete Mosaic system while fulfilling the Abrahamic hope. Philosophical and Behavioral Insight Human performance invariably falls short (Romans 3:23). Behavioral science confirms moral inability: no culture produces flawless obedience. The law therefore exposes need; promise supplies remedy. Only a grace-based inheritance resolves cognitive dissonance between moral aspiration and actual behavior. Archaeological Corroboration • Ketef Hinnom silver scrolls (7th century BC) quote the priestly blessing (Numbers 6:24-26), proving Mosaic texts were revered yet never portrayed as salvific in themselves. • Merneptah Stele (c. 1208 BC) attests Israel’s presence in Canaan—consistent with a people whose identity was formed around promise long before full law codification reached final form. Practical Implications for the Modern Reader 1. Security: The inheritance rests on God’s unwavering promise, not fluctuating performance. 2. Unity: Jew and Gentile receive the same inheritance by faith (Galatians 3:28). 3. Freedom: Law as a condemning power is displaced; believers serve in newness of Spirit (Romans 7:6). Summary The inheritance in Galatians 3:18 is not based on the law because the promise to Abraham predates, overrides, and outclasses the Mosaic covenant. God’s irrevocable, grace-grounded oath secures the inheritance; the law’s temporary, diagnostic role cannot supplant it. Receiving that inheritance remains, now as always, a matter of faith in the crucified and risen Messiah, the singular Seed of Abraham (Galatians 3:16). |
