Borrowed from athletic contexts where δρόμος meant a footrace or the course itself, the word takes on rich metaphorical meaning in Paul's ministry reflections. He speaks of 'finishing the race' or 'completing the course' as a way to describe faithful completion of apostolic calling. The image combines the ideas of a defined path, sustained effort, and a finish line—all apt for describing the Christian ministry or life itself as a purposeful journey from start to completion.
