God’s Covenant Will Last Forever

Reading time: 5 minutes

When God makes a promise, He never fails to keep it. All His covenants are ultimately fulfilled in Jesus (2 Corinthians 1:20). Jesus is the first in everything; He defeated death when God resurrected Him. All believers will follow after Jesus and be raised to eternal life. God promised us the New Covenant which will last forever.

And I will make him the firstborn,
    the highest of the kings of the earth.
My steadfast love I will keep for him forever,
    and my covenant will stand firm for him.
I will establish his offspring forever
    and his throne as the days of the heavens.

Psalm 89:27-29 ESV

God’s Covenant Means He Disciplines But Does Not Abandon His Children

In Acts 13:34, Paul calls Christ the sure blessings of David; this covenant was confirmed by God in Christ; the law could not annul it or make the promise of it of no effect. How can the children of this covenant fall away and be lost forever? God might discipline them, but never stop loving them.

If [the children of this covenant] do not obey my decrees
    and fail to keep my commands,
then I will punish their sin with the rod,
    and their disobedience with beating.
But I will never stop loving him
    nor fail to keep my promise to him.

Psalm 89:31-33 NLT

Now, does God’s faithfulness to His Son demand that His children (redeemed by His blood) shall be saved? Unquestionably it does because His word says that He will not stop loving them.

I will not violate my covenant
    or alter the word that went forth from my lips.
Once for all I have sworn by my holiness;
    I will not lie to David (Christ).
His offspring shall endure forever,
    his throne as long as the sun before me.

Psalm 89:34-36 ESV

The author of Hebrews refers to the same when he says:

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, 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 have this as a sure and steadfast anchor of the soul, a hope that enters into the inner place behind the curtain, where Jesus has gone as a forerunner on our behalf, having become a high priest forever after the order of Melchizedek.

Hebrews 6:17-20 ESV

How, I ask, is this covenant mutable? Can it be altered or changed? No, it is immutable; the oath of God secures it, and all is confirmed in Christ. Therefore, the blood of Christ is called “the blood of the everlasting covenant;” this covenant is called the book of life of the Lamb slain from the foundation of the world.

This truth gives them confidence that they have eternal life, which God—who does not lie—promised them before the world began.

Titus 1:2 NLT

God, who cannot lie, promised eternal life before the world began; also, grace was given to us in Christ before the world began, and we were chosen in him before the foundation of the world. This proves the existence of an everlasting covenant, which is related not only to the crucifixion of Jesus, but to the eternal salvation of all His children; and not only is the death of Jesus a subject of appointment in this covenant, but also the result of His death. So David could say:

Is it not my family God has chosen?
    Yes, he has made an everlasting covenant with me.
His agreement is arranged and guaranteed in every detail.
    He will ensure my safety and success.

2 Samuel 23:5 NLT

Nothing about Jesus’s death — its time, manner, and purpose — was left uncertain.

But Israel is saved by the Lord
    with everlasting salvation;
you shall not be put to shame or confounded
    to all eternity.

Isaiah 45:17 ESV

Here is salvation certain, that shall reach even to eternity.

God’s Covenant Means He Does Not Forget or Fail to Fulfill His Promises

Can a woman forget her nursing child,
    that she should have no compassion on the son of her womb?
Even these may forget,
    yet I will not forget you.
Behold, I have engraved you on the palms of my hands;
    your walls are continually before me.

Isaiah 49:15-16 ESV

God uses a powerful illustration here. Do these words look as if fading from grace is possible? No, not until God lies under oath, nor until the everlasting covenant is annulled, nor until Christ, who is one in covenant with us, is dragged down from His throne of power, and hurled into hell. God made Christ a high priest forever…

• after the order of Melchisedec (Hebrews 6:20)
• over the house of God (Hebrews 10:21)
• by the power of an endless life (Hebrews 7:16)

As a priest of this order, and over this house, He procures endless life. He is the captain, to bring many sons to glory. For this work, He is made perfect through suffering. He is the wisdom, righteousness, sanctification, and redemption of all His people; He will be to them a God, and they shall be to Him a people. From what we have seen, the salvation of God’s people depends on the success of Christ as the surety of the better testament; and as he cannot fail, the salvation of all his people is certain.

The New Covenant is such good news because of all that Jesus has fulfilled for us believers. The security of your faith, of your very life, is only as strong as the object of your faith. If your faith is fully in Christ, you will experience full assurance of your salvation.
