The life truly is in the blood, but not in a chalice.  
DNA. 

There were two trees and two seeds in the garden. One seed was created; the other begotten by Lucifer. As firstborn the birthright went to Cain. It was stolen by the Hebrew Priests and later the Roman Church. 
At endtimes the birthright will be restored.

The begotten bloodline of Cain inherited life. The created line inherits death.

The entire history of the world is the political struggle between the descendants of Cain and the descendants of Adam. It's fueled by the enmity placed between them in Genesis 3:15.
That enmity was and still is over the inheritance. 

The majority of the populations of Europe, Scandinavia and North America are descendants of Cain by blood. These are the three regions being invaded by immigrants right now. 

It's not coincidence. This is a war.
