(1Corinthians 11:3) But I would have you know, that the head of every man is Christ; and the head of the woman [is] the man; and the head of Christ [is] God.
God’s order of authority in marriage (the family structure) never changes. Although the wife may be more intelligent and resourceful than her husband, God still wants her to look to him as her leader.
Here's an example where Paul was guided by both husband and wife:
(Acts 18:26) And he (Paul) began to speak boldly in the synagogue: whom when Aquila and Priscilla had heard, they took him unto [them], and expounded unto him the way of God more perfectly. -- Priscilla, was not competing with Aquila. She was just using her God-given abilities, to support her husband for the glory of God.
However, the Holy Spirit leads the way as to where and when a woman preaches/teaches.
It is expected of all of us to contribute spiritually to the lives of others. And it shall be as the Holy Spirit dictates.
