Do you realize that ADONAI chooses whomever He chooses to be His servant in some way? It doesn't matter whether we're male or female, rich or poor, old or young, black, white, red, brown, red or yellow - HE USES WHOMEVER He WILL! Halleluyah!
Remember - In Genesis 12, YHWH chose Abram, a pagan Chaldean, to become our first Patriarch! And, starting in Exodus 2, we see Moshe being prepared to go to Egypt to liberate YHWH's people (he was 80 years old at that point), lead them through the desert wilderness for 40 years and write the entire Torah!
In the days when there was an absence of "good men," YHWH chose a WOMAN to be Judge over all Israel (see the Book of Judges) - which, to me, puts an end to the argument that women need to "be silent" or that they can't teach men. That's totally bogus! YHWH chooses whoever He knows can and will meet HIS needs.
He chose Rav Sha'ul (Paul) to become the Apostle to the Gentiles ... Paul, who was a raving anti-missionary and murderer! (See Acts 9.)
And today, He is choosing some of US to promote His Word. No matter who we are or what we've done in the past, it simply doesn't matter. It's who we are NOW in Him that matters - Halleluyah!
Here's are some passages (in random order) and from random sources that prove that it:
Joel 2:28 And afterward, I will pour out My Spirit on all people. Your sons and daughters will prophesy, your old men will dream dreams, your young men will see visions. 29 Even on My menservants and maidservants, I will pour out My Spirit in those days.…
Acts 2:17 In the last days, God says, I will pour out My Spirit on all people. Your sons and daughters will prophesy, your young men will see visions, your old men will dream dreams.
Isaiah 44:3 For I will pour water on the thirsty land, and currents on the dry ground; I will pour out My Spirit on your descendants, and My blessing on your offspring.
Ezekiel 36:27 And I will put My Spirit within you and cause you to walk in My statutes and to carefully observe My ordinances.
Proverbs 1:23 Turn you at my reproof: behold, I will pour out my spirit unto you, I will make known my words unto you.
There are many more passages, but you get the gist: YHWH uses whomever He wishes, whenever He wishes - so listen to that "small, still voice" and be ready at all times!
