The original designers of the US constitution knew that absolute power corrupts absolutely, so they separated the powers to prevent the demise of the country. The Legislative branch writes the laws, the Executive branch enforces the laws and the Judicial branch interprets the laws.

In the garden, Satan questioned God’s Legislative branch (Did God really say, you must not eat from any tree in the garden? Gen 3:1). Then he attacked God’s Executive branch (You certainly will not die! Gen 3:4) and finally the Judicial branch (For God knows that when you eat from it your eyes will be opened and you will be like God, knowing good and evil Gen 3:5). Satan wants all men to be their own god because he knows absolute power corrupts absolutely. Fulfillment can only come when we submit to Christ and follow God’s principles Gal 2:20.
