God never wanted humans to have a king.
He wanted to be worshiped and adored Himself as a God and King. Israel (His people) demanded to have a physical king as other nations.
What Political Science has become is an excretion of what religion and government (law) has reflected over thousands of years.
We still as children of God are to submit ourselves to the worldly authority of this land, since it is a fact that we chose to have an Earthly Kingdom (thus; Israel chose to have a king rather than simply honor God as husband & king).
There is nothing more pleasing to God than for humans to live humble, good lives and enjoy themselves while here on this Earth.
I Timothy 2:1-4-I urge, then, first of all, that petitions, prayers, intercession and thanksgiving be made for all – for kings and all those in authority, that we may live peaceful and quiet lives in all godliness and holiness. This is good, and pleases God our Savior who wants all people to be saved and come to the knowledge of the truth.
Can we do this with the leadership we choose to have and follow while here on Earth?...
Our salvation depends on it.
