According to Paul in Corinthians the gospel message could only be lifeless when Christians
Answer Details
In Corinthians, Paul argues that the gospel message can only be ineffective or "lifeless" for Christians if they deny the message of resurrection. In other words, if Christians do not believe in the resurrection of Christ, then the gospel message loses its power and meaning.
Paul also discusses other problematic behaviors among Christians that can hinder the effectiveness of the gospel message, such as persecuting one another, gossiping, and entertaining idolatrous practices. However, these actions are not specifically mentioned as causing the gospel message to be lifeless.
