Leadership needs to be confirmed by God and others. Jesus was not a self-proclaimed leader, God confirmed His leadership. People easily fall into the temptation to become self-proclaimed leaders.
Leadership is about more than having a position. Leaders need to be competent, have integrity, and display selflessness. Jesus has set the example for us.
Leaders can take people much further when they willingly follow than when they are told authoritatively to follow. Both Jesus and Nehemiah motivated people to follow.
