Excellent Question!!
When we set about to get a proper Biblical answer there ae some things we must remember when rightly dividing the word of God.
First answer the questions:
Who wrote the book?
Who was the book written to?
What is the time frame of the Book?
Is there anywhere else in the Bible where is topic is covered?
In this example in I Tim, we have the Apostle Paul teaching a younger preacher, Tmothy, about "Church" governement and authority; meaning this is reserved for the Biblical church.
Lets look at other scriptures about the same topic:
I Cor 11 also is about authority but it says that a womans long hair is given to her for WHEN she prays or prophecies - prophecying there means preaching.
So now you have "in the church" women - preaching.
As to teaching - it was the womans ROLE to teach the children and the seniour ladies to teach the younger women.
Another note Jesus appeared to over 500 after his resurrection and on the day of Pentecost there were women in the upper room who had received the great commision as well as the men.
Also Jesus set women free from being a "second class citizen", this whole topic of subserviant/submission is usually taught by a man who is abusive and not from a true biblical perspective.
So to answer your question ...
If the man is not in the Biblical Church of Jesus Christ - I have a commandment to preach to him the gospel of Christ. If he asks me a question I will answer it. If I can I will share my testimony and if I am called on to preach the Word (either in the church or out) I will.
If the man is in the Biblical Church of Jesus Christ - I will share a testimony or truth or if I have the authority given to me by my husband and pastor I will preach and teach as the Lord leads, as long as I remain under that protective umbrella of spiritual authority I'm free.
There is neither Jew nor Greek, there is neither slave nor free man, there is
neither male nor female; for you are all one in Christ Jesus. Gal 3:28
I hope this helps this is just a quick answer to a huge question for women - the bottom line is that Satan has managed to quench 1/2 of the voice of the Christian church by misguided teachings.
God Bless,
