Isaiah 55

“Hey! Come, everyone who thirsts, to the waters! Come, he who has no money, buy, and eat! Yes, come, buy wine and milk without money and without price.

Why do you spend money for that which is not bread, and your labor for that which doesn’t satisfy? Listen diligently to me, and eat that which is good, and let your soul delight itself in richness.

Turn your ear, and come to me. Hear, and your soul will live. I will make an everlasting covenant with you, even the sure mercies of David.

Behold, I have given him for a witness to the peoples, a leader and commander to the peoples.

Behold, you shall call a nation that you don’t know; and a nation that didn’t know you shall run to you, because of the LORD your God, and for the Holy One of Israel; for he has glorified you.”

Seek the LORD while he may be found. Call on him while he is near.

Let the wicked forsake his way, and the unrighteous man his thoughts. Let him return to the LORD, and he will have mercy on him, to our God, for he will freely pardon.

“For my thoughts are not your thoughts, and your ways are not my ways,” says the LORD.

“For as the heavens are higher than the earth, so are my ways higher than your ways, and my thoughts than your thoughts.

For as the rain comes down and the snow from the sky, and doesn’t return there, but waters the earth, and makes it grow and bud, and gives seed to the sower and bread to the eater;

so is my word that goes out of my mouth: it will not return to me void, but it will accomplish that which I please, and it will prosper in the thing I sent it to do.

For you shall go out with joy, and be led out with peace. The mountains and the hills will break out before you into singing; and all the trees of the fields will clap their hands.

Instead of the thorn the cypress tree will come up; and instead of the brier the myrtle tree will come up. It will make a name for the LORD, for an everlasting sign that will not be cut off.”

Overview.
This chapter is a gospel-like invitation from the LORD to the spiritually thirsty and economically destitute to receive life and sustenance freely through His covenant mercy. Centered on the promise of an everlasting covenant rooted in the "sure mercies of David," it calls for repentance, assures the efficacy of God’s word, and culminates in a vision of cosmic renewal. Positioned in the latter part of Isaiah’s prophetic vision, it functions as both a climax to the message of comfort and a forward-looking summons to trust in God’s redemptive purposes.

Flow.

Begins with a striking call to the thirsty and penniless to come and receive water, wine, and milk—images of spiritual nourishment—without cost (v. 1–2).
Shifts to a covenantal promise: God offers life and an unbreakable covenant grounded in David’s messianic lineage, extending salvation to nations unknown (v. 3–5).
Calls for repentance and return to the LORD, emphasizing His readiness to pardon abundantly (v. 6–7), then reveals the divine transcendence: God’s thoughts and ways surpass human understanding (v. 8–9).
Concludes with a natural metaphor: as rain and snow accomplish God’s purpose in the earth, so His word will unfailingly achieve redemption, resulting in joy, peace, and transformed creation (v. 10–13).

Connections.
Following chapter 54, which celebrates Zion’s expansion and God’s steadfast covenant love, chapter 55 deepens the call to participate in that covenant by urging all to seek the LORD while He is near. It answers the earlier assurance of restoration with a summons to individual and communal response. Its emphasis on the power and purpose of God’s word prepares the reader for chapter 56, which opens the door to inclusion for foreigners and eunuchs who keep the covenant—demonstrating how the promised blessings are accessed by faith and obedience rather than lineage alone.

What it teaches.
God freely offers spiritual life and covenant fellowship to all who respond in faith, regardless of moral or economic worth, grounded not in human effort but in His sovereign mercy (WCF 7.3; HC LD 23). The "sure mercies of David" point to a future King through whom the covenant extends to all nations (WCF 8.6; Canons of Dort I.6). God calls sinners to repent not because they can earn salvation, but because He delights to pardon (WCF 15.1; HC Q&A 86). His word is effectual, accomplishing His redemptive will as surely as rain waters the earth (WCF 1.8). The transformation of creation—thorns becoming cypress and briers becoming myrtle—signals a final renewal that will stand as an everlasting testimony to God’s glory (WCF 13.3; HC Q&A 57).

Apply.
Come empty-handed to God’s promise, trusting that His word will accomplish what He intends in your life.
