Summary: All our hope and doctrine hangs on the fact that Jesus doesn’t change!
We’ll continue our study through Hebrews picking up at 13:8:
Jesus Christ the same yesterday, and to day, and for ever.
This verse seems a little bit out of place and it almost appears to stand alone. Maybe it’s sort of like one of the many Proverbs that have no connection with each other besides the fact that they appear on the same page. But that’s not the case, and in fact, the exact opposite is true. This verse is a summary of the book and the pinion for its doctrine.
The context shows how Christ has been faithful to all the men and women in Old Testament history and, more immediately, to our leaders: “Whose faith follow, considering the end of their conversation.” We talked about that last time—“doctrine for life and death.” Well, the Jesus that they trusted and preached is the same yesterday, today, and forever! If He was faithful to them, then we can be absolutely certain that He’ll be faithful to us. This is why we follow their faith. It’s not because they were great, but because Christ is!
And I want you to notice this: He’s not only faithful yesterday and today. He’s faithful forever. We get our English word “eon” from the Greek word used here. If you go forward in time 1 million years He’ll still be faithful. Go ahead another 10 trillion years and He’s still just as faithful. He never gets tired of us or of keeping His word. He never changes in mind, purpose, or nature.
This is where we get the doctrine of the perseverance of the saints or eternal security. Some people say, “You mean you can do whatever you want and you’ll still get to go to heaven?” And that just shows a misunderstanding of the nature of Christ. You see, it was never about my righteousness in the first place. God made a promise to Adam and Eve to send a Redeemer. He confirmed the promise to Abraham and his Seed and then He delivered Christ. Christ has promised not to lose a single one of the children given unto Him, and He’s promised to take us to be with Him in eternity. I don’t deserve any of it, and I never can. But I’m not trusting in myself; I’m trusting in His faithfulness. If we believe not, yet he abideth faithful: he cannot deny himself” (II Timothy 2:13).
When God was speaking to His people through Malachi He promised to purge the Levites and to judge the wicked. Then He says, “I am the LORD, I change not; therefore ye sons of Jacob are not consumed” (Mal. 3:3-6). That word “therefore” may be the most important word in the sentence. The sons of Jacob are not consumed with the rest of the wicked simply because the Lord does not change. If He did change then they would have been in some serious trouble.
Another thing: we worry about the future and we really worry about our children, but doesn’t this verse teach us that God will be as faithful to them as He has been to us? He’s a better Father than we could ever be. The church is in no danger and human history is in no more danger than it’s ever been. There’s a day coming when everything will be judged and burned and the righteous will be delivered, and you can bet the Judge of all the earth knows how to keep and reserve everything in its place until that final day.
