The Pharisee stood by himself and prayed: 'God, I thank you that I am not like other people--robbers, evildoers, adulterers--or even like this tax collector. - Luke 18:11
Leaders who think they are God's own cousin while masquerading as the most knowledgeable, aren't realistic about their personality. When a leader throws his weight around as Mr. Know-It-All, it would be a tall order for such a leader to acknowledge his weakness. Some leaders don't want to acknowledge that they are vulnerable in some areas because they want to be seen as Mr. Know It All or Mr. Flawless. Consequently, they prefer to beat their brains out than to ask for help especially when their knowledge gap is staring them in the face.
Acknowledging your weakness as a leader shouldn't be seen as a sore point. The upsides of doing this is to enable you connect with people and establish a common ground with your team. More so, it would help you to leverage their support and help your team to play to their strengths when they pitch in and help. In 2 Samuel 24, when King David balked at the advice of Joab, Chief of Israel Army, who tried to prevail on the king against undertaking a census of the children of Israel, the king fell out of favour with God. The census sparked off a divine wrath against the king because he undermined the potency, supremacy and faithfulness of God in safeguarding and multiplying His people. This sends the message that leaders who assume absolute and universal knowledge would most likely despise the repertoire of skills their team bring to the table. It's also in character for them to make light of offers to help them out of grim situations.
The Pharisees, who had a scrape with Jesus, struggled with submitting themselves to His authority. They would rather go under the name of "the most perfect", proclaiming that they have unbeatable track record of fasting, prayers and devotion to the Law. So when they ought to have acknowledged Jesus as the King of Glory, they masterminded His crucifixion. They felt it beneath them to see Jesus as the Messiah because they struggled with reconciling His humble background with His divine identity. This unenviable attribute has made many leaders to throw caution to the wind and despise wise counsel. Hence, when leaders don't keep an open mind, while assuming to know it all, they would mute the zeal of other to pitch in and help with innovative approach and would of course get their fingers burnt. May the Lord bestow you with an open mind which would endorse your leadership with credibility and influence in Jesus name
