A SOLEMN CALL TO True Humiliation.  
FAsting, Fasting and Mourning is called for: And the cause why Fasting and Mourning is called for, is; because of the great and universal Apostasy from the Life and Power of Godliness that hath been, and that still is, in this our Age. And though the Apostasy hath been great, yet, there are some Nathaniels that are in sadness, and grieved for it. And unless Purity and Holiness be brought forth amongst you, all your Preaching, and all your Hearing, is in vain. For, a perfect, and entire Resignation is called for, and required [by the LORD] of all, that, this Day, makes mention of His Name.  
Thou shalt love the LORD thy GOD with all thine Heart, with all thy Soul, with all thy Might, and with all thy Strength, and thy Neighbour as thyself.
