Sometimes weakness will manifest in leaders doing things they should not be doing, or things they are simply unsuited to do. At other times, weakness may result in leaders avoiding things they really ought to do.
Weaknesses can get in the way of leadership. However, we often do not talk about another side to weaknesses in leaders. That is, a leader who focuses on her weaknesses to the extent that she does not lead from her strengths?
Moses and Gideon are two good biblical examples of such leaders. When God called Moses to lead the children of Israel out from under the bondage of slavery in Egypt, Moses pointed to his weakness (Ex. 4:10) as the reason he could not (or should not) be the one to lead the children of Israel.
From the beginning of Chapter 3 up to Chapter 4:9, God has been demonstrating to Moses His great power to do miracles. But when called upon to lead, Moses’s response was to point to his weakness saying, “Pardon your servant, Lord. I have never been eloquent, neither in the past nor since you have spoken to your servant. I am slow of speech and tongue.”
