Just because it's never been done, doesn't mean it can't be done! They key in Nehemiah's story is that even when the critics showed up and caused trouble, He never came off the wall and kept working. He didn't let the critics stop him from doing what God put in his heart!
Read Nehemiah 4:1-14
The reality is this, anytime you are doing something great, something worthwhile, you will encounter critics. Count on it!
"There is only one way to avoid criticism: do nothing, say nothing and be nothing!" Aristotle
It will work every time...But, if you choose this method, you will miss out on seeing God do great things in you and through you. Leaders, the critics are part of the journey. And, if you call yourself a leader there will never be a shortage.
Would you rather face a critic or the possibility of never achieving something great?
