Martha discusses what "Her Character" should be when an older woman begins to mentor a younger women.
When an older woman befriends a younger woman, she is likely to influence the younger women's thinking and actions. That can be good news or bad news. For example, it is bad news when the older woman leads the younger women into heresy. It is good news when the older woman is doctrinally sound. It is bad news when the older woman rebels against the authority of the elders in her church or her husband. It is good news when she is graciously under their authority. It is bad news when the older woman is a gossip. It is good news when she is like the "holy women of old". (1 peter 3:5)
Obviously, God does not want an older woman to be a bad influence on the younger women. Instead, he wants her to have godly character listed in Titus 2:3-5.
Older women likewise are to be reverent in behavior, not slanderers or slaves to much wine. They are to teach what is good, and so train the young women to love their husbands and children, to be self-controlled, pure, working at home, kind, and submissive to their own husbands, that the word of God may not be reviled.
Regardless of our ages, we can all learn to be a Titus 2 woman..and we can eventually become an older woman who truly does "teach what is good" and "encourage younger women".
