“The [next] metaphor presents the preacher as ‘a worker who does not need to be ashamed’ because he ‘handles the word of truth’ skillfully (2 Tim. 2:15). In other contexts, the Greek verb used here means ‘able to cut a straight path through country that is forested or difficult to pass through so that a traveller can go directly to his destination.’ This straight teaching contrasts with the false teaching of those who swerve from the truth (2 Tim. 2:18), ESV). Our exposition must be faithful and simple so that our hearers can understand and follow it easily.”
