I would sit under Kay Arthur's teaching any day of the week, as the old saying goes.
There are lots of excellant women bible teachers that both women AND men have been blessed to learn from.
AiC
One problem is when women take over teaching, some men hate going to church and stop going to church. This seems to be pretty prevelant these days.
Women often do lead and teach their husbands, to become involved at church and provide leadership at church.
Behind every man is a woman who is making him what he is.
Women generally have better intuition than men, and this is sometimes true of spiritual things too. Getting the men to discover spiritual things is a much bigger challenge.
These might be reasons why God commanded what He did in the Bible, but I'm just speculating.
He set up men as the leaders and teachers.
Sometimes I tell my kids to teach others in their class in math, or physics, or any hard subject, because then they will learn it better themselves.
Maybe God knew men needed to teach, so they would learn it.
Maybe God had to pick one gender to be responsible and accountable in the home to do certain roles, and that's how he picked it.
Whaterver the reason, we don't know and God didn't say all the reasons, but by faith and grace we obey, while respecting and valuing both genders exactly equally the same.
