Jesus Christ Is the Same Yesterday Today and Forever | Hebrews 13:8 Explained

People change. They change their minds. They change their commitments. They change their affections.

People change their minds — their favorite food, favorite music, even their favorite people. For instance, changing taste in cuisine is called culture, but changing affection for people is often labeled disloyalty.

People hesitate to commit. Why? Because commitments bind. They limit future options. Anyone who has tried to recruit volunteers understands this tension.

“Let me think about it.” “I’m not sure about my schedule.” “What if something else comes up?”

Affections shift just as quickly. Consider middle school friendships: one week, you are inseparable; the next, you sit alone at lunch. It’s a familiar scene.

When I consider the instability of the human heart, I take comfort in what Scripture says about God:

God is not human, that he should lie, not a human being, that he should change his mind. Does he speak and then not act? Does he promise and not fulfill (Numbers 23:19)?

Balaam’s oracle emphasizes that God’s declared purposes are not subject to revision.

And,

“For God’s gifts and His call are irrevocable” (Romans 11:29).

Here, Paul is speaking specifically of God’s covenant promises to Israel — promises that He does not revoke.

God does not fluctuate as we do. His purposes stand.

Last time we reflected on God’s immutability — His unchanging nature. He is not like shifting shadows (James 1:17).

Following our reflection on God’s immutability, this week we look at that same unchanging nature in the person of Jesus Christ.

The original audience of Hebrews was under pressure—tempted to add to Christ or rely again on the Law. After declaring Christ’s constancy, the author warns against teachings that undermine the sufficiency of Christ’s work, reminding them that Christ’s sacrifice was once for all and needs no repetition. Jesus Christ—fully God and fully man—remains constant in His nature, His character, and His saving purpose.

He is the Same Yesterday

Even before he walked the dusty roads of Galilee, He was. Scripture tells us that:

“In the beginning was the Word, and the Word was with God, and the Word was God. He was with God in the beginning” (John 1:1-2)

“He is before all things, and in him all things hold together (Colossians 1:17).

Jesus declares that He and the Father are one (John 10:30). Jesus is God; God does not change. Neither does Jesus.

The One who calmed the storms in the first century is the eternal Son who has always been.

He Is The Same Today

Jesus is not absent.

Jesus promised that He would be with us until the end of the age (Matthew 28:20).

Although we cannot see Him, we take comfort knowing that He is with us through His Spirit, interceding for us with the Father (Hebrews 4:14-16; 7:25) and sympathizing with our weaknesses (Hebrews 4:15).

The reason His intercession is effective is that He lives forever and His priesthood lasts forever (Hebrews 7:24).

He Is the Same Forever

Because Jesus does not go back on His Word, because He made a once-for-all sacrifice (Hebrews 10:14), and because He does not release what He has already redeemed, we can look forward to the day when we are with Him forever (1 Thess 4:17).

As followers of Christ, who never changes, we can rely on His promises, knowing that He does not take back what His sacrifice has secured, unlike human reliability, which often falters.

Conclusion

People change their minds, but Christ does not reconsider His promises.

“Whoever comes to Me I will never cast out” (John 6:37).

He who promised is faithful (Hebrews 10:23).

People change their commitments. Christ does not.

His sacrifice does not expire.

By one offering, He has perfected for all time those who are being sanctified (Hebrews 10:14).

He does not return to the cross because nothing more is needed.

People change their affections. Christ does not.

Nothing can separate us from the love of God in Christ Jesus (Romans 8:38-39). He does not withdraw from those He has redeemed.

No one will snatch them out of His hand (John 10:28).

In a world of shifting loyalties and unstable hearts, our hope is anchored in this truth: Jesus Christ is the same yesterday, today, and forever.

Because He does not change, we do not vacillate.

Because He is sufficient, we do not add.

Because He is faithful, we hold fast.
