1. Train yourself to be godly (6-10).
A good minister directs and nourishes God's people with God's truth. But this requires training one's self to be godly, avoiding myths and old wives' tales, focusing on the truths of the faith and of the good teaching one received. Exercise keeps our body healthy, to be ready for what comes. But godliness has value for all things. We need to take responsibility for our spiritual health, training to be aware of and imitate God.
2. Set a good example (11-16)
If the good minister is growing in the faith, they are able to give a good example. True leadership comes from example and influence, not position or charisma. But this requires diligence and wholeheartedness, as well as transparency, so all will see the progress. To avoid hypocrisy, we must watch that faith and doctrine are aligned; that we practice what we preach. Doing so saves ourselves and our hearers.
