1 Corinthians 15:20
But now is Christ risen from the dead
As was before proved by ocular testimonies, and before preached and asserted; and now reassumed and concluded, from the glaring contradictions, and dreadful absurdities that follow the denial of it:
and became the firstfruits of them that slept;
who were already fallen asleep; respecting chiefly the saints that died before the resurrection of Christ; and if Christ was the firstfruit of them, there is no difficulty of conceiving how he is the firstfruits of those that die since. The allusion is to the firstfruits of the earth, which were offered to the Lord: and especially to the sheaf of the firstfruits, which was waved by the priest before him, ( Deuteronomy 26:2 ) ( Leviticus 23:10 Leviticus 23:11 ) and to which Christ, in his resurrection from the dead, is here compared. The firstfruits were what first sprung out of the earth, were soonest ripe, and were first reaped and gathered in, and then offered unto the Lord; so Christ first rose from the dead, and ascended to heaven, and presented himself to God; as the representative of his people; for though there were others that were raised before him, as the widow of Sarepta's son by Elijah, the Shunammite's son by Elisha, and the man that touched the prophet's bones when put into his grave, and Jairus's daughter, the widow of Naam's son, and Lazarus by Christ; yet as these did not rise by their own power, so only to a mortal life: but Christ, as he raised himself by his own power, so he rose again to an immortal life, and was the first that ever did so; he was the first to whom God showed, and who first trod this path of life. The firstfruits were the best, what was then ripest, and so most valuable; Christ is the first, and rose the first in dignity, as well as in time; he rose as the head of the body, as the firstborn, the beginning, that in all things he might have, and appear to have, as he ought to have, the pre-eminence. The firstfruits sanctified the rest of the harvest, represented the whole, gave right to the ingathering of it, and ensured it; Christ by lying in the grave, and rising out of it, sanctified it for his people, and in his resurrection represented them; they rose with him, and in him; and their resurrection is secured by his; because he lives, they shall live also. The firstfruits were only such, and all this to the fruits of the earth, that were of the same kind with them, not to tares and chaff, to briers and thorns; so Christ, in rising from the dead, is only the firstfruits of the saints; of such as are the fruits of his death and of his grace, who have the fruits of his Spirit in them, and are filled with the fruits of righteousness by him; just as he is the firstborn from the dead, with respect to the many brethren, whom he stands in the relation of a firstborn: once more, as the allusion is particularly to the sheaf of the firstfruits, it is to be observed, that that was waved before the Lord, the morrow after the sabbath, ( Leviticus 23:11 ) which, as the Jews F6 interpret, was the morrow after the first good day, or festival of the passover; the passover was on the fourteenth day of the month; the festival, or Chagiga, on the fifteenth, and which, in the year that Christ suffered, was a sabbath day also; and the morrow after that, the sheaf of the firstfruits was waved; now Christ suffered on the passover, rested in the grave on the seventh day sabbath, and on the morrow after that, rose from the dead, the very day that the first fruits were offered to the Lord: so that the allusion and phrase are very appropriately used by the apostle.
