This sermon explores the divine attribute of immutability, asserting that God is unchangeable in His being, nature, and purposes. By contrasting the inherent instability of human life with the constancy of God, the message emphasizes that God's perfect wisdom and power preclude any possibility of improvement or deterioration. The text highlights that while God's dealings with humanity may appear to shift, His underlying covenant and promises remain fixed, providing a secure foundation for belief. For the believer, this truth serves as a source of profound comfort, assurance of salvation, and confidence in prayer, knowing that God's love and faithfulness endure despite personal failings or external circumstances. Finally, the sermon invites listeners to rest their souls on the unchanging character of God, who remains the same yesterday, today, and forever.
