I was reading a book and I found a quote on Farmers- " Farmers don't Just work till the sun goes down, They work till the Job Gets done" isn't it so true of this Quote.
"Paul returned to the theme of examples in verse 4-7. Here the examples are three models taken from secular life- the soldier, the athlete, and the farmer. Paul used the same three example in 1 Corinthians 9. there the examples of the soldier and the farmer illustrated how the workman is worthy of his hire (1 Cor 9:7). In 2 Timothy the main emphases are on hardship and effort and on future reward. The soldier gives his undivided attention and loyalty to his commanding officer and does not allow himself to be distracted by outside concerns. The soldiers of Christ likewise concentrate on His commander, Christ. The athlete competes by the rules. in the Olympic games, the rule prescribed a rigorous training period of ten months before one could participate in the games (Pausanias, Description of Greece 5.24.9). The successful athlete received a victor's crown. The farmer likewise could expect to receive from the fruits of his labor. The idea of reward was present in each of Paul's metaphors: the faithful servant of Christ can expect the eschatological reward. But the ideas of concentrated service, discipline, and hardship are the strongest emphases in the three metaphors. The servant of Christ can expect a share in hardship."
