15:2

if you hold firmly to the good news: The resurrection, part of “the primary doctrine” of Christianity, was under attack in Corinth. (Heb 6:1, 2) Some were arguing that “there is no resurrection of the dead.” (1Co 15:12) Paul drew attention to those who said: “Let us eat and drink, for tomorrow we are to die.” (1Co 15:32) He may have been quoting Isa 22:13, but those words well reflected the thinking of people influenced by such Greek philosophers as Epicurus, who denied that there was life after death. (Ac 17:32; see study note on 1Co 15:32.) Or some in the congregation who were of Jewish background may have been influenced by the beliefs of the Sadducees, who denied the resurrection. (Mr 12:18) Another possibility is that some felt that living Christians had already experienced some kind of spiritual resurrection. (2Ti 2:16-18) If the Corinthians failed to “hold firmly to the good news,” they would become believers for nothing​—their hope would not be fulfilled.​—See study note on 1Co 15:12.
