Titus 2:1-6
These instructions are an overall exhortation for the various age groups to hold to a sense of duty with regard to their conduct. But none of the instructions given here should be ignored simply because they are not addressed directly to an individual's sex or age group. For example, Paul says "girls should be discreet and modest." Does this mean, then, because it is addressed to girls that a fellow may be as indiscreet and immodest as he wants because he is male? Simply because the fellows are not mentioned does not excuse them from being discreet and modest as well. In an overall sense, God is telling all of us—parents, young people, male, female—to be sane, sober-thinking, serious about our responsibilities, exercising self-control, curbing our passions, and aiming for self-mastery.
There is a proverb that teaches: "He that rules his spirit is better than he who takes a city." Ruling one's spirit involves self-discipline. Self-discipline is willing yourself to do the right, regardless of feelings. It may not be glamorous, but it is the stuff of life.

Sanctification and the Teens

Sound doctrine is more than a gospel about Christ; it is the gospel of Christ, what He taught and lived and what He expects His followers to practice. His doctrine is "the pattern of sound words," the body of truth once for all delivered to the saints, giving the church a solid foundation against constant false doctrines. Paul supplies Titus a curriculum tailored to each age group and circumstance, since older and younger members stand at different points in conversion. Older, God-fearing members, including older women teaching younger women, lead by example and exhortation. Though addressed to specific groups, the instructions apply to all: be sober-minded, self-controlled, and responsible, ruling one's spirit by willing to do right regardless of feelings.
