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.
We are to love God with heart, mind and soul. In other words our total being should be dedicated to God and subjected to His will if we want to be good stewards of His property.
