Vcitory over Death
The trumpet blast “intensifies the metaphor of suddenness, adding the dimension of divine decree and ordered signal.” The trumpet is the sign of the Day of the Lord
Paul concludes with an exhortation introduced by the affectionate address, “my beloved brothers.” His appeal to the Corinthians is to be steadfast and immovable, complementary terms qualified by the phrase “always abounding in the work of the Lord,” and followed by the grounds “because you know that your labor in the Lord is not in vain.” Paul’s language harks back to the chapter’s opening where he reminded them of the gospel they received and in which they stand and where he urged them to hold fast to the word he proclaimed to them lest they believed in vain (15:1–2). To “stand firm” in this context is to hold fast to the gospel and to the belief in the resurrection that the gospel proclaims. Otherwise they have believed in vain. Having established the fact of resurrection as central to God’s redemptive plan, Paul concludes by urging them to rid themselves of the belief that there is “no resurrection of the dead” and to prosper in the work of the gospel knowing that all such work is not in vain (cf. 15:10, 14).
