What does it mean that Jesus Christ is the same yesterday, today, and forever?

When Scripture states that Jesus Christ is the same yesterday, today, and forever, it emphasizes His unchanging nature and the reliability of His promises. Found in Hebrews 13:8, this phrase assures believers that the same saving grace and love experienced in the past remain available today and will continue indefinitely. It is a profound comfort for Christians, especially amid life's uncertainties, because it reinforces that their salvation and relationship with God are secure, anchored in the eternal character of Christ.
