Introverted Leaders?

Here's an article that I came across today that makes a case for effective leadership by people who are introverted.

Interesting.  Pastor Randy Pope, whose church numbers in the thousands, is also an introvert from what I am told.  God can use all sorts of people to lead, but the power and authority of a leader in God's kingdom flows from their relationship with the Lord.  Was Moses introverted?  I don't know, but I do know that early on, in his attempts to lead the people of Israel, the people rejected him -- and so he ran (also because Pharaoh wanted to arrest him for murder).  And throughout their time in the wilderness, time and time again people questioned the authority of Moses, even his own sister and brother.  Yet, it was God who time and time again established Moses as the leader of His people.  It was Moses' relationship with the Lord that made the difference.  And another thing to note is that this relationship with the Lord was based upon grace.  Moses was called by God into this amazing relationship just because God wanted to (Exodus 3:10-17) -- even when Moses came up with all sorts of excuses.  God was gracious to Moses.
