I object to your insulting personal remark.
You say Esau was blessed and offer Genesis for support.
Since Esau was not blessed by God and was instead cursed by God and hated by God as later chapters in both the OT and NT illustrate, it makes a lot of sense to suggest that you read the rest of the book since it would appear that you've stopped at the first chapter.
When the horrid WCF is trotted forth, one may reasonably expect that there is no other resort. The WCF portrays a vindictive and juvenile Reformed God that picks the arms and legs off humans like little boys do to flies. It then portrays those humans condemned to death as their own fault.
The Reformed God creates sin and the devil to distribute it, yet disclaims all responsibility for creating that sin.
The theology of death which condemns, not the theology of life which was preached by Jesus and spread by the Apostles and the Church.
