Temperance
Temperance avoids excesses, especially areas that distract us from a godly life.
What makes temperance important to the Christian life?
Answers range from one person to the next, but the fact remains that Paul and Peter identify the need for Christians to grow in temperance.
Consider how the definition factors into leadership. A lack of temperance indicates the potential of participating to excess in areas that destroy the godly influence leaders need.
Growing in temperance indicates a life of balance. Leaders with temperance understand limits, specifically limits established by God to protect us physically and spiritually.
