“Know this for a certainty that today, the penetrative power in the arteries of the world of humanity is the power of the Covenant. The body of the world will not be moved through any power except through the power of the Covenant. There is no other power like unto this. This Spirit of the Covenant is the real Center of love and is reflecting its rays to all parts of the globe, which are resuscitating and regenerating man and illuminating the path to the Divine Kingdom."
