first always prayerfully see Scripture - God called / chose women for His Purpose all through history according to His Word.
then
also prayerfully and checking everything with Scripture, always, see how God chose women at different times and what they did, simply obeying Him, and He watched over His Word and always brought it to pass. (like Esther , by obeying God, saving the Jews).
admittedly awkward, and literally 'if you can stomach it' , watch some women today, if God permits, who are preaching or teaching on tv. check what they say with Scripture, and when possible see if they have trained any true disciples in the discipline of God's Word and Life in Jesus Christ.
...
yes 'if you can stomach it' is , well, a necessary observation due to the widespread corruption in men and women, not just women, and a lot of what is televised is abominable and quite directly opposed to Scripture and to God's Directions.
...
(that narrows it down a lot, to the few who remain faithful and true to God and to His Word).
...
even more narrow - if we don't do and don't learn to do what God says daily, live His Way according to His directions (like little children watching their Father and doing what He does, not like scholars studying then picking what they want to do! ),
then we won't be able to tell if someone else, man or woman, is 'right ruling' in their speaking/ teaching / preaching.....
a few women have been faithful teachers or given testimonies of God's Faithfulness and His Word. not many. a few.
the same is true of men. not many have been faithful and true. but a few have been. test everything. check Scripture prayerfully. there is no other provision in God's Plan other than by His Word.
