What does the Bible say about the unchanging nature of Jesus?

The concept of the unchanging nature of Jesus is foundational in the Christian faith as indicated in Hebrews 13:8, which states, 'Jesus Christ is the same yesterday, today, and forever.' This assertion underscores the idea that while the world and cultures may change, the character, promises, and purposes of Christ remain constant for all believers. The previous verses in Hebrews 13 suggest that we are to remember and respect those who have spoken the Word of God to us, thus reinforcing that the teachings and gospel they preached point to this immutable Christ. His unchanging nature provides reassurance and a foundation for faith amidst the ever-changing circumstances of life.
