This word “immutability” refers to the unchangeableness of God. Immutable means unchangeable, impossible to change. Mutation is something that can change. God cannot change because He has no need to change. He is perfect in all His ways.
Numbers 23:19 – “God is not a man, that He should lie, nor a son of man, that He should repent.”
1 Samuel 15:29 – “And also the Strength of Israel will not lie nor relent. For He is not a man, that He should relent.”
Malachi 3:6 – “For I am the LORD, I do not change.”
The book of Hebrews was written to tell the Jews that if they didn’t stop acting like Hebrews they would only end up being Hebrews. In other words: It was written to people who knew the law. And because of that, the writer begins with a foundation that many Gentiles didn’t have.
Hebrews 6:13 – For when God made a promise to Abraham because He could swear by no one greater, He swore by Himself, (Verse 14) saying, “Surely blessing I will bless you, and multiplying I will multiply you.” (Verse 15) And so, after he had patiently endured, he obtained the promise.
(Verse 16) For men indeed swear by the greater, and an oath for confirmation is for them an end of all dispute. (Verse 17) Thus God, determining to show more abundantly to the heirs of promise the immutability of His counsel, confirmed it by an oath,
(Verse 18) that by two immutable things, in which it is impossible for God to lie, we might have strong consolation, who have fled for refuge to lay hold of the hope set before us. (Verse 19) This hope we have as an anchor of the soul, both sure and steadfast, and which enters the Presence behind the veil, (Verse 20) where the forerunner has entered for us, even Jesus, having become High Priest forever according to the order of Melchizedek.
So this hope that we have is based on that God can’t change and He can’t lie, anchors our soul. This is our emotions, what we’re thinking and how we are feeling.
So if we understand when we are going through a battle that God can’t change, then we have an anchor in the storm. This word immutability and immutable is only seen two times in the Bible and it’s in Hebrews Chapter 6. We have to understand that it’s impossible for God to lie or change.
When we take an oath, we have to swear by someone greater than ourselves. This tradition comes from Jewdisim. God had no one greater than Himself to swear by so the covenant that He made with Abraham, He swore by Himself.
Hebrews 6:17 (NASB) In the same way God, desiring, even more, to show to the heirs of the promise the unchangeableness of His promise.
Who are the heirs of the promise? Romans 4:13 – For the promise that he would be the heir of the world was not to Abraham or to his seed through the law, but through the righteousness of faith. (Verse 14) For if those who are of the law are heirs, faith is made void and the promise made of no effect.
In the same way that God made an oath, covenant, with Abraham, this is the new covenant by which God took an oath and He can’t lie. The new covenant is grace! What are the things in the new covenant that God can’t change?
Jesus is our Hig Priest forever.
Hebrews 6:20 – where the forerunner has entered for us, even Jesus, having become High Priest forever according to the order of Melchizedek.
Hebrews 7:17 – For He testifies: “You are a priest forever according to the order of Melchizedek.” (This is also stated in Psalm 110:4.)
Hebrews 7:23 – And there were many priests because they were prevented by death from continuing. (Verse 24) But He, because He continues forever, has an unchangeable priesthood.
There is no possibility of Jesus not remaining High Priest for those who believe in Him. He’s our High Priest forever. All other priest died before, but Jesus lives and remains forever.
Hebrews 10:11 – And every priest stands ministering daily and offering repeatedly the same sacrifices, which can never take away sins. But this man, after He had offered one sacrifice for sins forever, sat down at the right hand of God, (Verse 13) from that time waiting till His enemies are made His footstool.
He sat down because it was finished! He will never die on the cross again. He lived a perfect life and died the perfect sacrifice. My question that I always wonder is: Who came up with the idea, if they know Scripture, why would there still be priests today? Do they not know that there is only One Priest and only that One could take away sin? All the other so-called priests in the world are useless. Nowhere in the New Testament after Jesus, does it say that priests should be appointed. That is man-made!
Is Jesus still your High Priest when you have a bad week?
Jesus is our Mediator of the New Covenant forever.
Hebrews 8:6 – But now He has obtained a more excellent ministry, inasmuch as He is also Mediator of a better covenant, which was established on better promises.
A better covenant with better promises. When you think of the Old Covenant, that’s the Mosaic covenant. Why is the New Covenant better than the old? Because the New can do something the Old cant’ do. It cleanses our sin, not just cover our sin! It cleanses us from all sin and unrighteousness. It can cleanse our conscience so we don’t serve God out of dead works. A dead work is a work done trying to earn the favor of God.
Hebrews 9:9 – It was symbolic for the present time in which both gifts and sacrifices are offered which cannot make him who performed the service perfect in regard to the conscience –
Hebrews 9:13 – For if the blood of bulls and goats and the ashes of a heifer sprinkling the unclean, sanctifies for purifying of the flesh, (Verse 14) how much more shall the blood of Christ, who through the eternal Spirit offered Himself without spot to God, purge your conscience from dead works to serve the living God? (Verse 15) And for this reason, He is the Mediator of the new covenant, by means of death, for the redemption of the transgressions under the first covenant, that those who are called may receive the promise of the eternal inheritance.
Hebrews 10:1 For the law, having a shadow of the good things to come, and not the very image of the things, can never with these same sacrifices, which they offer continually year by year, make those who approach perfect. (Verse 2) For then would they not have ceased to be offered? For the worshipers, once purged, would have had no more consciousness of sins.
This verse is not talking about being perfect in our performance. It’s talking about our position with God. Does the church focus on Grace consciousness enough or is it focused too much on our failures and sin? We will become like what we focus on – success, because of what Jesus has done – or failure because we ware weak.
In comparing the Old Covenant and the New: In the Old, God wrote the law down in the book of Leviticus and the book of Deuteronomy and the people said they would follow it. But before Moses even got down from the mountain, they broke it.
However, in the New Covenant, God says, “I’m going to love you, protect you, provide for you, and forgive all your sin even though you will not be perfect in your ways.” Our part of this new covenant is to believe and accept the One and only sacrifice that was made by His Son and then and only then can we enter into a covenant with Jesus.
