I was wondering what the term Zion means to us today as Christians. I am confused here. It seems in the Old Testament Zion was Jerusalem or more specifically The Jebusite fortress on Mount Moriah(?). Zion being the City of David.
When we sing or read the Psalms where they mention Zion what is the doctrinal understanding we are to presume? My "opinion" is that Zion is either the present Heavenly Kingdom or the Kingdom that Christ will usher in at His return. How close am I to the right answer?
Plus, any resources that could shed light would be great.
