Are you accustomed to thinking of presidents as the highest level of political power? In some countries a prime minister holds the corresponding office, but in most modern countries even the top official has limited power.
They are open to criticism and opposition. In ancient times this was not so and kings had tremendous power in their own kingdoms. Yet who is worthy to exercise unlimited power? I am not the president of the Kingdom of Heaven, I am the King. All heaven declares that I am worthy and one day all earth will as well. You are a citizen and subject of my Kingdom and it is your privilege to do so now.
