How do we know Jesus is the same yesterday, today, and forever?

The assertion that 'Jesus Christ is the same yesterday, today, and forever' (Hebrews 13:8) underscores His divine nature and eternal constancy. This principle reveals that His character, authority, and salvation are unalterable. Throughout the Scriptures, we see that He remains faithful and true, and His purpose of saving His people is secured eternally. By reflecting on His role as Prophet, Priest, and King, we can understand that His immutability reinforces the security believers have in their salvation, as He will always fulfill His promises.
