What other scriptures affirm God's unchanging nature and promises? Starting Point: The Oath to Abraham (Hebrews 6:13) “When God made His promise to Abraham, since He had no one greater to swear by, He swore by Himself.” The writer of Hebrews anchors our confidence in God’s immutability by recalling the moment God bound Himself to His word with an oath. Because He is perfect, eternal, and sovereign, there is no higher authority than God Himself to guarantee the promise. From that single verse, Scripture opens a rich trail of passages that highlight the same unchanging character and rock-solid faithfulness. Old Testament Foundations of God’s Unchanging Nature • Malachi 3:6 — “Because I, the LORD, do not change, you descendants of Jacob have not been destroyed.” • Numbers 23:19 — “God is not a man, that He should lie, nor a son of man, that He should change His mind. Does He speak and not act? Does He promise and not fulfill?” • Psalm 89:34 — “I will not violate My covenant or alter the utterance of My lips.” • Psalm 102:25-27 — “They will perish, but You remain… But You remain the same, and Your years will never end.” • Psalm 119:89-90 — “Your word, O LORD, is everlasting; it is firmly fixed in the heavens. Your faithfulness continues through all generations.” • Isaiah 40:8 — “The grass withers and the flowers fall, but the word of our God stands forever.” • Isaiah 46:9-11 — “My purpose will stand, and I will do all that I please… Truly I have spoken, truly I will bring it to pass.” • Lamentations 3:22-23 — “Because of the LORD’s loving devotion we are not consumed… great is Your faithfulness!” New Testament Echoes of the Same Certainty • Hebrews 6:17-18 — “So when God wanted to make the unchangeable nature of His purpose very clear… He confirmed it with an oath. Thus by two unchangeable things in which it is impossible for God to lie…” • James 1:17 — “Every good and perfect gift is from above… with whom there is no change or shifting shadow.” • Titus 1:2 — “…in the hope of eternal life, which God, who cannot lie, promised before time began.” • 2 Timothy 2:13 — “If we are faithless, He remains faithful; for He cannot deny Himself.” • 2 Corinthians 1:20 — “For all the promises of God are ‘Yes’ in Christ. And so through Him, our ‘Amen’ is spoken to the glory of God.” • Hebrews 10:23 — “Let us hold resolutely to the hope we profess, for He who promised is faithful.” • 1 Thessalonians 5:24 — “The One who calls you is faithful, and He will do it.” • Romans 11:29 — “For God’s gifts and His call are irrevocable.” • Revelation 21:5 — “Write this down, for these words are faithful and true.” Why These Passages Matter to Us Today • They remove uncertainty. Because God does not change, the promise to Abraham—and every promise since—stands firm. • They establish a sure foundation for faith. His unchanging nature means today’s believer is anchored to the same God who spoke the universe into existence. • They inspire perseverance. Hebrews points to God’s oath so that “we who have fled to take hold of the hope set before us may be strongly encouraged” (6:18). • They guarantee future grace. A God who cannot lie secures both present help and eternal life for everyone trusting in Christ. The storyline of Scripture—from Abraham’s covenant to the final declaration in Revelation—beats with a single, steady theme: God keeps His word because He never changes. |
