This sermon presents a foundational, comforting truth for believers: amidst the constant flux of life, nine essential realities remain unchanging. Central to this message is the unchanging character of God, whose steadfastness is affirmed through Scripture, including Psalm 102 and Malachi 3:6, grounding all hope in His eternal faithfulness. The sermon emphasizes that God's Word, promises, and the person of Jesus Christ—declared unchanging in Hebrews 13:8—are the immutable pillars of faith. It further affirms that God's righteous anger toward unrighteousness, the enduring necessity of Christ, the perpetual need for divine wisdom, the unchanging call to worship, and the certain return of Christ are all fixed realities. By anchoring life in these eternal truths, the preacher calls listeners to find peace, security, and purpose in a world of change, urging them to fix their hearts on the unchanging God and His eternal promises.
