Certainly if you study heretics and listen to arrogant preachers who do not study and give their congregations a big dose of SYI then yes that is true. However if you study to show yourself approved to God then that is a different story. One who studies to be approved by God is not satisfied with getting his ears tickled by what he finds palatable with but rather knowing the truth and let the politics fall where they may. That man will not be liked by any religious politician. Religious politicians like parties not men of integrity and truth.
From the International Standard Bible Encyclopedia
Preacher, preaching -([tl,h,qo, qoheleth], “preacher” (Ecclesiastes 1:1), [rc”B;, basar], “to bring or tell good tidings” (Psalm 40:9; Isaiah 61:1), [ar;q;, qara’], “to call,” “proclaim”
(Nehemiah 6:7; Jon 3:2), [ha;yriq], qeri’ah], “cry,” “preaching” (Jon 3:2); [kh>rux, kerux], “crier,” “herald” (1 Timothy 2:7), [khru>ssw, kerusso], “to cry or proclaim as a herald” (Matthew 3:1; Romans 10:14), [eujaggelli>zw, euaggellizo], “to announce good news”
(Matthew 11:5)
<prof’-et-es> ([ha;ybin], nebhi’ah]; [profh~tiv, prophetis]): Women were not excluded from the prophetic office in the Old Testament, and were honored with the right of prophetic utterance in the New Testament. It should be noted, however, that women like Miriam (Exodus 15:20), Deborah (Judges 4:4) and Huldah (2 Kings 22:14) were not credited with the seer’s insight into the future, but were called “prophetesses” because of the poetical inspiration of their speech. Among others mentioned as having the prophetic gift we find Hannah (1 Samuel 2:1), Anna (Luke 2:36) and the four daughters of Philip (Acts 21:8,9).
A good start is with studying the history of the early church and its practices. Prophetesses were female. I don't think it is rocket science to understand that. Prophetesses and prophets spoke for God to the people. That is preaching in its most basic usage. Preaching is telling the people God's message.
The bible says that we are to go . . .
Let me just try to understand what you are saying in a practical sense. So according to your reasoning it is the right thing for you to do to go to a female dorm room to preach the gospel to a female student because that is something that only a man can do?
