This adjective describes what cannot be moved from its place, being immovable or unshakeable. In 1 Corinthians 15:58, Paul exhorts believers to be 'steadfast, immovable' in the Lord's work. Classical Greek used it for physical immobility and figuratively for personal steadfastness. The multilingual glosses (Spanish 'inconmovibles', French 'inébranlable', German 'unerschuetterlich') emphasize both physical and moral stability. Paul's call to unmoved perseverance concludes his resurrection chapter, grounding steadfast service in confidence that resurrection makes labor eternally meaningful.
