Look up how Wikipedia defines the word dictator and read on with an open mind. The association of God and the word DICTATOR is thought provoking. I have struggled with thoughts like this and numerous other thoughts about God. Why is He? Where is He? Which is He? What is He? When is He? And finally who is He?
GOD as a Dictator is a RULER who ASSUMES SOLE and ABSOLUTE POWER with CONTROL but, without HEREDITARY ASCENSION.
Ascensions and or (heritage) lineage of God are not traceable by any form of science, except by FAITH. We still don't know where He came from. He is the beginning and the end. Everything and thought as we can know and understand starts and ends with Him. We grapple at scenarios and thoughts as to God's origin but that is a futile exercise. We know many people occupied this universe and for sure God was before them. We know we shall surely die one day, and after we are gone to where ever, God will still be everywhere He so chooses. History even at times cannot trace the origin of some great people and I don't think it will satisfy the hereditary ascension of God.
HE IS THE SOLE RULER:
God does what He wants, when He wants to do it, how He wants to do it, how many times He wants to do it, at anytime, anywhere and He does not have to ask permission from anyone including me or you. Don't be offended by such a dogmatic and arrogant statement because truth and reality bears witness to this statement. Sometimes don't you have moments where you want to question God? Bring Him to bear for what you are experiencing? He can choose to answer, ignore or teach you something about what he is doing. Why is it so? Because HE CAN, HE HAS ABSOLUTE POWER with CONTROL:
This is why He can! Let us look at 3 important words. ABSOLUTE (loosened from limitation or condition, complete in itself). POWER (Power refers broadly to any ability to effect change or exert control over either things or people). CONTROL (Control is used in a variety of contexts to express "mastery" or "proficiency"). Yes that is why He is the sole ruler. He has the absolute power and control. This is not a human dictator who might have military power and control for a while. That is why human beings cannot compare to the ultimate dictator.
Without limitation or condition and with mastery and proficiency, God is complete in Himself to effect change or exert control over thoughts, things or people! That is why it is said so many times "The fear of God is the beginning of wisdom".
