John is a strange liar.

He lies on six days of the week, but on the seventh day, he always tells the truth.

My first is present - future's past -
A time in which your lot is cast.

My second is my first of space
Defining people's present place.

My whole describes a lack of site -
A place without length, breadth, or height.
