Titus 2 describes older women training younger ones, and for years I read that as a one-directional flow — wisdom moving downhill, from the more experienced to the less. Mentoring actual mothers has corrected that assumption more times than I can count.
A young mother I once counseled through her first hard nursing season later modeled, for me, a kind of unhurried patience with her toddler that I had to relearn myself. Another taught me, without meaning to, what genuine dependence on God looks like when you have no other options left. The training Paul describes is real, and I do lead it deliberately. But I have never left one of those relationships without receiving as much as I gave.
