The Earnest of Our Inheritance

Devotional

Day 1: The Spirit’s Seal: Assurance in a Groaning World

You are marked as God’s own. The Holy Spirit’s sealing isn’t a vague religious idea but a divine guarantee, a stamp of ownership on your life. This truth anchors believers amid life’s uncertainties, reminding them their identity isn’t rooted in fleeting circumstances but in Christ’s finished work. The Spirit’s presence testifies that you belong to God, even when your faith feels fragile. This sealing began the moment you believed, a permanent mark of grace. Its purpose? To steady your heart until the day every tear is wiped away. [00:49]

“In him you also, when you heard the word of truth, the gospel of your salvation, and believed in him, were sealed with the promised Holy Spirit, who is the guarantee of our inheritance until we acquire possession of it, to the praise of his glory.” (Ephesians 1:13–14, ESV)

Reflection: When doubts about your salvation arise, what tangible evidence does the Spirit’s sealing provide? How might this truth reshape your response to failure or fear?

Day 2: The Earnest: Heaven’s First Installment

The Holy Spirit isn’t merely a down payment—He’s the first taste of eternity. Like sampling ripe fruit from a future harvest, the Spirit gives glimpses of glory here and now. His joy, peace, and love aren’t diluted previews but the genuine essence of what’s to come. Every moment of communion with God, every surge of grace under pressure, is a fragment of your inheritance. This earnest assures you the full weight of heaven’s riches awaits, undiminished and eternal. [12:16]

“And it is God who establishes us with you in Christ, and has anointed us, and who has also put his seal on us and given us his Spirit in our hearts as a guarantee.” (2 Corinthians 1:21–22, ESV)

Reflection: Where have you tasted “heaven’s flavor” this week—in worship, service, or quiet prayer? How does this foretaste strengthen your endurance in trials?

Day 3: Broken Walls: Gentiles Sealed as God’s Heirs

Peter’s prejudice shattered when the Spirit fell on Cornelius. Tongues of fire on Gentile believers proved God’s family transcended ethnic lines. The early church’s greatest scandal became its greatest testimony: the Spirit recognizes no second-class citizens. Your place in God’s household isn’t earned through pedigree or performance. The same Spirit that sealed Jewish apostles seals you, making former outsiders coheirs of promises older than Abraham. [04:35]

“While Peter was still saying these things, the Holy Spirit fell on all who heard the word. And the believers from among the circumcised who had come with Peter were amazed, because the gift of the Holy Spirit was poured out even on the Gentiles.” (Acts 10:44–45, ESV)

Reflection: What invisible “circumcision” barriers do you unconsciously uphold? How does the Spirit’s work in others challenge your assumptions about who belongs?

Day 4: Groaning with Guaranteed Hope

Christian groaning isn’t despair—it’s the ache of a body stamped with eternity yet still battling sin. The Spirit’s presence amplifies this tension, making you restless for full redemption. Your sighs over personal failures, relational fractures, or global brokenness are proof the earnest is at work. These groans are birth pains, not death rattles, assuring you that the Spirit’s firstfruits guarantee a harvest of wholeness. [30:15]

“And not only the creation, but we ourselves, who have the firstfruits of the Spirit, groan inwardly as we wait eagerly for adoption as sons, the redemption of our bodies.” (Romans 8:23, ESV)

Reflection: What specific “groan” in your life feels heaviest today? How does the Spirit’s role as firstfruits transform how you carry this weight?

Day 5: Mirrors and Mountains: Seeing Glory’s Reflection

You gaze at Christ’s glory through the dim mirror of the Spirit’s work—not face-to-face, yet truly. Every act of love, every victory over sin, every glimpse of divine beauty in Scripture or creation is the Spirit holding up that mirror. These reflections aren’t vague spiritual sentiments but actual particles of eternity at work in you. One day the mirror will shatter, leaving only the blinding reality of His presence. Until then, the Spirit bends the light of heaven into your now. [34:01]

“And we all, with unveiled face, beholding the glory of the Lord, are being transformed into the same image from one degree of glory to another. For this comes from the Lord who is the Spirit.” (2 Corinthians 3:18, ESV)

Reflection: When has the “mirror” of God’s glory startled you recently? How does this gradual transformation affirm the Spirit’s work as both earnest and artist?

Sermon Summary

Paul takes Ephesians 1:14 as a further addition to the great statement already begun in verse 13. God’s grand purpose is that, in the fullness of times, all things in heaven and earth should be gathered together in Christ, and the church is already the visible proof that this plan is in operation. The bringing together of Jews and Gentiles into one body is not a small matter, but an astounding manifestation of God’s design. God has proved that Gentiles are fellow heirs by giving them the same Holy Spirit given to Jewish believers.

The sealing of the Spirit gives God’s people that peculiar and exceptional assurance that they are the children of God. The Spirit bears witness with their spirits, and God sets his seal upon them. Yet Paul does not merely repeat himself when he says that the Spirit is “the earnest of our inheritance.” The word “earnest” means more than guarantee. It is a pledge, yes, but it is also an installment in kind, a first payment of the very thing that is to come.

The earnest is therefore richer than a mere pledge. A pledge may be something different from the thing promised, but an earnest is part of the thing itself. The Holy Spirit is not simply a token that heaven will be given later. The Holy Spirit brings a real foretaste of the inheritance now. Modern translations that reduce the word to “guarantee” lose something of the fullness of Paul’s thought.

Redemption here means the final completion of God’s purpose, the entire emancipation and deliverance purchased by the blood of Christ. The seal assures the believer that he is an inheritor. The earnest gives assurance concerning the inheritance itself, because it gives something of the thing promised. The Spirit dwelling in the body is the pledge that the mortal body itself shall be quickened and redeemed. The Christian still groans, as Paul says, because the body is not yet delivered from sin, but the firstfruits of the Spirit guarantee the harvest.

The Spirit also gives a foretaste of heaven. Heaven means seeing Christ and becoming like him. Now the sight is “through a glass darkly,” yet it is still a true sight of his glory. Now holiness, love, joy, and peace are only firstfruits, but they are real firstfruits. The Holy Spirit brings celestial fruit on earthly ground, so that Christian people begin even now to taste the inheritance that will be full at the redemption of the purchased possession.

Key Takeaways

1. The Spirit is more than guarantee The word “earnest” carries a fullness that “guarantee” alone cannot bear. The Spirit is not merely evidence that something else will one day arrive, but the first installment of the inheritance itself. Heaven is not only promised from afar; something of its own nature is already given in the Spirit. [16:26]
2. Redemption means the completed deliverance Redemption is not exhausted by forgiveness, though forgiveness is gloriously included. Paul’s word points to the final consummation, when Christ’s ransom has brought the purchased possession into full liberty. The blood of Christ has secured not a partial rescue, but an entire emancipation of soul and body. [22:11]
3. The body also shall be redeemed The Spirit dwelling within the believer is the pledge that the mortal body will not be abandoned to sin and death. Groaning is not unbelief when it longs for the redemption of the body; it is part of apostolic Christianity. The firstfruits of the Spirit make present weakness bearable because they point to a complete harvest still to come. [30:15]
4. Heaven begins as a foretaste Heaven’s essence is seeing Christ and becoming like him. The present sight is through a glass darkly, yet it is still the real glory reflected by the Spirit. The earnest of the Spirit means that the life of heaven has already begun, though only in measure and not yet in fullness. [38:18]
5. Holiness becomes present enjoyment The Spirit gives not only a hatred of sin, but a joy in purity, righteousness, and the commandments of God. Holiness is not mere restraint; it is the first taste of the world where nothing defiling can enter. The soul that has the firstfruits begins to love what heaven loves and abhor what heaven excludes.

Bible Reading

Ephesians 1:13-14
“In him you also, when you heard the word of truth, the gospel of your salvation, and believed in him, were sealed with the promised Holy Spirit, who is the guarantee of our inheritance until we acquire possession of it, to the praise of his glory.” [00:00:07]

Romans 8:23
“And not only the creation, but we ourselves, who have the firstfruits of the Spirit, groan inwardly as we wait eagerly for adoption as sons, the redemption of our bodies.” [00:30:01]

2 Corinthians 3:18
“And we all, with unveiled face, beholding the glory of the Lord, are being transformed into the same image from one degree of glory to another. For this comes from the Lord who is the Spirit.” [00:36:35]

1 Corinthians 13:12
“For now we see in a mirror dimly, but then face to face. Now I know in part; then I shall know fully, even as I have been fully known.” [00:37:30]

Observation questions

In Ephesians 1:13-14, what happens after people hear the word of truth and believe in Christ, and what two things are said about the Holy Spirit in these verses? [00:07:30]
What difference is drawn between being “sealed” by the Spirit and having the Spirit as “the earnest” of the inheritance? [00:26:02]
According to Romans 8:23, what do believers already have, and what are they still waiting for? [00:30:15]
In 2 Corinthians 3:18 and 1 Corinthians 13:12, what words show both a present sight of Christ’s glory and an incomplete sight that will one day become full? [00:38:18]

Interpretation questions

If the Spirit is not only a guarantee but also the first installment of the inheritance itself, how does that deepen the meaning of Ephesians 1:14? [00:16:26]
Paul speaks of redemption as something still future in its fullness. How does that help explain why a Christian can be truly saved and yet still groan? [00:22:11]
The Spirit’s presence in the believer is tied to the future redemption of the body. How does that shape the way suffering, weakness, and the ongoing struggle with sin should be understood? [00:29:33]
Heaven is described chiefly as seeing Christ and becoming like him. How do 2 Corinthians 3:18 and 1 Corinthians 13:12 show that this has already begun, though only in part? [00:38:45]

Application questions

Many believers find it easier to think of heaven as a distant promise than as something already tasted in the Spirit. Where has there been even a small foretaste of Christ’s joy, peace, or holiness in life recently? [00:34:03]
The Christian life includes groaning for the redemption of the body. Is there any area of weakness, sickness, temptation, or weariness where there is a need to remember that the body itself will also be redeemed? [00:30:15]
Holiness is not only duty but delight. Is obedience to God’s commands mostly felt as burden, or is there growing joy in what is pure and right? What may help that joy grow? [00:41:34]
Seeing Christ now is “through a glass darkly,” yet it is still real. What practices or settings most help fix the heart on Christ so that his glory is more clearly seen? [00:37:30]
If the Spirit gives the firstfruits of heaven now, how might love for other believers become a more visible part of ordinary life this week? [00:43:08]
Peace in the Holy Spirit is meant to be known even in changing circumstances. In what present situation is there a need to seek that peace instead of being ruled by fear or restlessness? [00:44:36]
The church is meant to be living proof that God is gathering all things together in Christ. Are there any barriers of suspicion, distance, pride, or difference that need to be faced so that this unity is more plainly seen? [00:05:29]

Sermon Clips

I'll tell you the chief things in heaven, the two chief things in heaven. Seeing him and becoming like him. That's heaven. That is the very essence of heaven. Blessed are the pure in heart, for they shall see God. Beloved, now are we the sons of God, and it does not yet appear what we shall be, but we know that when he shall appear, we shall see him. We shall be like him. For we shall see him as he is. That's heaven. [00:34:50]

And that is what we have in this life and in this world, the firstfruits of the great harvest that awaits us. Or, if you prefer it, you can think of it as a foretaste. It's the same thing exactly. You just take a sample, you take a specimen, you just take a little. You don't take it all yet, but you have something to wet your appetite. You have something to give you enjoyment, something to ravish your heart and to move you. That's what the earnest of the spirit is. [00:33:28]

He that raised up Christ from the dead shall also quicken your immortal bodies by his spirit that dwelleth in you. If the spirit is in you, you've got an earnest. You've got a first disk. You've got a first installment of what's going to happen to you completely. There is a day coming when your very body shall be entirely delivered from sin, and you've got a guarantee of that by the presence of the spirit within your body. [00:29:16]

And he teaches that if we are truly Christian, we should know something of this groaning. Though we have the first fruits of the Spirit, we groan within ourselves, waiting for the adoption, to wit, the redemption of our body. Yes, and the presence of the Spirit of the first fruits within us is a guarantee that that is really going to happen, and that our bodies really are going to be finally redeemed from all sin. [00:30:42]

It is only as we understand this kind of doctrine that we can be truly established. And the whole purpose of doctrine is not merely to give us intellectual understanding or satisfaction. It is to establish us. To make us firm, to make us solid Christians, to make us unmovable, to make us have such a foundation that nothing can shake us. [00:11:24]

God gave a positive proof of the fact that the Gentiles really were fellow heirs. And that proof was the giving of the Holy Spirit. The sealing with the Spirit. Now that's why the Apostle introduces this whole subject at this point. He's concerned, I say, primarily to say that God is putting into operation this great plan of unification. Jews and Gentiles are brought together in the church and there's no doubt about it. It's beyond doubt. God has given proof of it by giving to the Gentiles the gift of the Holy Ghost exactly as he had already given it to the Jewish believers. It was the final proof. [00:05:15]

Now, there is a tendency on the part of some people to think of redemption only in terms of forgiveness of sins, but it isn't. It is sometimes, and the context will generally make it perfectly plain as to which it is. But obviously, in that quotation I've just given, redemption means the final consummation. The end. He's wisdom. He's our righteousness. There's your justification and forgiveness. He's sanctification and redemption. The whole thing. The completed purpose. The entire emancipation and deliverance. [00:21:50]

The seal is that which assures me that I am an inheritor. It gives me an assurance with regard to myself with respect to the inheritance. That's a seal. That's what the sealing of the Holy Spirit does. What then is the inheritance? Well, if you like, the inheritor the earnest is that which gives me an assurance with regard to the thing itself. It gives me something of the thing itself. [00:26:02]

But then face to face. But thank God what I am seeing now is a part of the same. It is an installment. It is the first fruits. It is the foretaste. It is an earnest. It's not only a guarantee. It's a part of the thing itself. I am entering into the glory in a measure even now. [00:38:22]

The characteristic of an earnest is that it is a part of the thing itself. It is an installment. It is a first payment in kind of the very thing itself. Now, that is, as I hope to show you, a very vital part of the understanding of this doctrine. That it is a kind of first installment of the whole that is to follow. [00:14:50]

Redemption does mean after all deliverance by means of the payment of a ransom price. And if you turn up even Greek English lexicons, you will find that the really great ones and standard ones bring out that as they explain this word. It is the ransom price of the blood of Christ that has been paid for our final redemption and deliverance. [00:22:31]

And surely if there is one need greater than any other at the present time, it is that Christian people should be established. And that we should learn to think of ourselves not so much in terms of particular experiences as in terms of our whole position. And that which God has planned and intended for us. [00:11:48]

That that is that peculiar exceptional assurance which God gives to his people. It is the spirit testifying with our spirits that we are the children of God. That's the sealing. [00:07:46]

The most astounding thing that has ever happened in a sense was the bringing bringing together, the coming together of Jews and Gentiles into one body called the church. Now, that was already taking place. [00:02:54]

The Holy Spirit is an installment given to us until we receive in all its fullness. I don't like the word acquire. Until we receive in all its fullness. What Christ has purchased for us by his own precious blood. [00:22:59]
