2 Tim 2:3-6
"Share in suffering as a good soldier of Christ Jesus. No soldier gets entangled in civilian pursuits, since his aim is to please the one who enlisted him. Also, if anyone competes as an athlete, he does not receive the victor’s crown unless he competes according to the rules. It is the hardworking farmer who ought to have the first share of the crops."
Three metaphors of ministry: (1) Soldier — focus, separation from the world, loyalty to the commander; (2) Athlete — discipline, rules, reward; (3) Farmer — hard work, patience, sharing in the fruits. Each metaphor illuminates a different aspect of faithful ministry.
