Paul gives Timothy four clear, active commands. Commentators explain them as: 1) 'Be sober' - stay clear-headed, self-controlled, and vigilant. 2) 'Endure hardship' - expect and patiently bear suffering for the gospel. 3) 'Do the work of an evangelist' - consistently proclaim the good news of salvation. 4) 'Fulfill your ministry' - carry out all your duties completely, leaving nothing undone. These form the essential job description for a faithful leader.
