How do we know that Christ never changes?

In contrast to earthly leaders like Joshua, who faced decline with age, the scriptures reveal that Christ remains eternally steadfast and unchanging. Hebrews 13:8 states that 'Jesus Christ is the same yesterday, today, and forever,' which reinforces the idea that He does not grow old or weak. His eternal nature assures believers that He is always equipped to save and intercede on our behalf. This consistency is paramount for our faith, as it provides the assurance that no matter the trials we face, Christ's capability and authority in our lives will never wane.
