firstfruits: the opening portion of a harvest handed over to God, which is both his share and the promise of everything still to come.
Israel's law required that the opening portion of a harvest go to God before anyone ate from it: the first sheaf of the barley, the first loaf baked from the new grain. That gift was never just a tax. It admitted that the whole crop was God's gift in the first place, and it treated the small part handed over as standing in for everything still out in the field. This word names that portion.
Every use in the New Testament is a picture, and all of them lean on the same two ideas: the portion belongs to God, and the portion promises more.
- The first believers in a province are the opening yield of a harvest still coming in.
- Christ raised is the first sheaf of a resurrection that will gather in his people.
- The Spirit given now is the opening share of an inheritance not yet handed over in full.
- A church already claimed by God is the part of creation that shows what he intends for the rest.
The double force is what gives the word its weight. Because the part is holy, the whole it speaks for is treated as holy too, which is how Paul can argue in Romans 11 from a holy first portion to a holy batch of dough. And because a first portion implies a later crop, calling Christ the first of those raised is a claim about everyone who belongs to him. Neither point survives if the word is heard as simply "the earliest" or "the best."
It sits near two other words without being either of them. The word for a firstborn son (πρωτότοκος) stresses rank and inheritance rather than an offering, and the business word for a deposit (ἀρραβών) promises the rest of a payment but carries no sense of something given to God.
