Paul first appealed to the Corinthians" logic. In this form of logic, called modus tollens, Paul"s argument was that since Christ was raised there is a resurrection of believers. That Paul had believers in view, rather than all people, seems clear in that he was discussing the hope of believers. Other passages teach the resurrection of other groups of people, even all others (e.g, Daniel 12:2; Revelation 20:4-5; Revelation 20:12; et al.). Here it becomes clear for the first time in the chapter that some of the Corinthians were saying that there is no resurrection of the dead. If they were correct, Christ did not arise, and they had neither a past nor a future. [source][source][source]
