The First Revelation, Chapter 5
Context: It needeth us to have knowing of the littleness of creatures and to hold as nought all-thing that is made, for to love and have God that is unmade. For this is the cause why we be not all in ease of heart and soul: that we seek here rest in those things that are so little, wherein is no rest, and know not our God that is All-mighty, All-wise, All-good. For He is the Very Rest. God willeth to be known, and it pleaseth Him that we rest in Him; for all that is beneath Him sufficeth not us. And this is the cause why that no soul is rested till it is made nought as to all things that are made. When it is willingly made nought, for love, to have Him that is all, then is it able to receive spiritual rest.
