Gods immutability our reason for certainty.

Lexham Survey of Theology God’s Immutability

God’s immutability is his freedom from change and his being the same at all times past, present, and future.

Lexham Survey of Theology God’s Immutability

The doctrine of divine immutability affirms God’s freedom from all change. Existing outside of time, he is all that he is in one unchanging moment, free from the movement and development of history. But within time, his creatures experience him as unchanging in his relations to human beings and therefore perfectly worthy of trust.

God shows his immutability in remaining perfectly faithful to his promises. What God wills he will do, and what he begins he will complete. God’s immutability is not an obstacle to human relationship to God but is the foundation for trust in him.

Hebrews 6:13 ESV

For when God made a promise to Abraham, since he had no one greater by whom to swear, he swore by himself,

In swearing by Himself he swore by his own integrity and unchangeable nature to do what he had promised.

Despite changes in life and circumstances and in our own emotions, Gods promises to us remain the same. We can count on him, that he will never change. Though all else does around us.

Hebrews 6:14–15 ESV

saying, “Surely I will bless you and multiply you.” And thus Abraham, having patiently waited, obtained the promise.

Our patience is rooted in Gods unchangeable nature. His immutability.

In a life of uncertainty, trusting in the immutability of God anchors our hope in Christ, who fulfills every promise and provides steadfastness and assurance amidst change.

Hebrews 6:16 ESV

For people swear by something greater than themselves, and in all their disputes an oath is final for confirmation.

Hebrews 6:17 ESV

So when God desired to show more convincingly to the heirs of the promise the unchangeable character of his purpose, he guaranteed it with an oath,

God wants us to have assurance, to root our trust in his unchangeable character.

A word of caution: Be careful about coming across as if we know everything. Be mindful of the tone of talking down to people. Just because we have assurance doesn’t mean other people do. We need to keep that in mind.

Hebrews 6:18 ESV

so that by two unchangeable things, in which it is impossible for God to lie, we who have fled for refuge might have strong encouragement to hold fast to the hope set before us.

We discovered that Gods promise and the oath are the two unchangeable things. God who is unchangeable reveals his nature in his words. When we hold onto his words we are holding onto his nature.

Hebrews 6:19 ESV

We have this as a sure and steadfast anchor of the soul, a hope that enters into the inner place behind the curtain,

The anchor was an ancient symbol of the early church. Picturing our trust in Christ. Think of it this way, our hope is in Jesus. where is he right now? He’s in the inner place, the holy of holies. Behind the curtain.

Hebrews 6:20 ESV

where Jesus has gone as a forerunner on our behalf, having become a high priest forever after the order of Melchizedek.

Believer’s Bible Commentary Apostasy

D. Anderson-Berry writes:The word translated “forerunner” is found nowhere else in the New Testament. This expresses an idea never contemplated in the Levitical economy, for the high priest entered the holiest only as a representative. He entered where none could follow. But our Forerunner is a pledge that where He is, we also shall be. As Forerunner He (1) announced our future arrival there; (2) took possession of heaven’s glories on our behalf; and (3) has gone to be able to bid His people welcome when they come, and to present them before the Majesty of heaven.9
