From Kwaku El, The Insecurity of Calvinism:

And perhaps such a personal insecurity resonates well with the God of Calvinism, a God that needed to prove his power, a God that created the world to boast in his own glory. A God that wasn’t secure in himself; and had to resort to bragging. A God that only loves the Calvinist or Christian, who’s theology the Calvinist approves of, and a God that only sent his son to die solely for the Calvinist or Christian, who’s theology the Calvinist approves of.
In this theology all naysayers can be disregarded. It isn’t that your theology is cruel, it isn’t that the beliefs hold a selfishness and anger toward the world, it’s just that God created them not to understand, and you’re simply better. All who disagree were made that way, but you were made to be one of the elect.
