Time of the heavenly resurrection. The heavenly resurrection of Christ’s joint heirs begins after Jesus Christ returns in heavenly glory, to give first attention to his spiritual brothers. Christ himself is called “the firstfruits of those who have fallen asleep in death.” Paul then says that each one will be resurrected in his own rank, “Christ the firstfruits, afterward those who belong to the Christ during his presence.” (1Co 15:20, 23) These, as “the house of God,” have been under judgment during their Christian life course, beginning with the first of their number at Pentecost. (1Pe 4:17) They are “certain [literally, some] firstfruits.” (Jas 1:18, Int; Re 14:4) Jesus Christ can be compared to the barley firstfruits offered by the Israelites on Nisan 16 (“Christ the firstfruits”), and his spiritual brothers as “firstfruits” (“certain firstfruits”) can be compared to the wheat firstfruits offered on Pentecost day, the 50th day from Nisan 16.​—Le 23:4-12, 15-20.

Peter writes to his brothers, pointing out that they, as “the house of God,” are under judgment, and he then quotes from Proverbs 11:31 (LXX) warning them of the danger of disobedience. He here implies that their present judgment could end with a judgment of everlasting destruction for them, just as Paul had written.​—1Pe 4:17, 18.
