KingJimmy,
There have been many times when godly women have shared a testimony with others and God has used it in a mighty way, such as the woman at the well in John 4 and Mary (as you mentioned). However, the verses that apply to this particular situation are as follows:
1 Timothy 2:11-15 (King James Version)
11. Let the woman learn in silence with all subjection. 12. But I suffer not a woman to teach, nor to usurp authority over the man, but to be in silence. 13. For Adam was first formed, then Eve. 14. And Adam was not deceived, but the woman being deceived was in the transgression. 15. Notwithstanding she shall be saved in childbearing, if they continue in faith and charity and holiness with sobriety.
When we look at the passage above and at 1 Corinthians 11 (which instructs women to wear head coverings when praying or prophecying) we may be tempted to think that it was something that was said to fit in with the culture of the day, but Paul makes it clear in the above passage that it was because of Adam and Eve that these things are necessary, not because of their current culture. (That is also true of 1 Cor. 11 when Paul says that it is "because of the angels" and "nature itself teaches you" about a women's head being covered. It had nothing to do with the culture of the day).
Preaching or teaching (it would be hard to seperate the two), is something that God has required from men. I know of certain situations where a man would not speak and so a women was used by God. But if we are striving for holiness and purity, then we should want to do what God wants us to do, not the second best. God has given women many gifts that men do not have and He even tells us in the Word when a woman should teach:
Titus 2:3-5 (King James Version)
3. The aged women likewise, that they be in behaviour as becometh holiness, not false accusers, not given to much wine, teachers of good things; 4. That they may teach the young women to be sober, to love their husbands, to love their children, 5. To be discreet, chaste, keepers at home, good, obedient to their own husbands, that the word of God be not blasphemed.
When older women teach younger women how to live a Godly life, I am sure it is a beautiful thing in God's sight. I interpret that as not just women who are older in age but who are more mature in their faith, they may teach new converts godliness also.
Please let me know if I have missed anything or if there are other scriptures on this issue and let us run this race according to the rules.
