God(father, son, holy spirit) is/are Spirits.. so are "we" and angels too(spirits)..
YES I am saying that.. What a spirt/Spirit really is, is to be determined..
Ghost is just an archaic english word for "spirit".. (whatever that is)..
However I just expanded on the "pearl" theme.. as Jesus did.. i.e. Lusting after a women is the same as raping her, hateing your brother is the same as KILLING him.. like that..
No doubt about it.. never was a human born on this planet that could take away the sin of the world.. Jesus is a pearl of great price.. and a special "pearl".. Thats not to say there not other "pearls".. Missing the metaphor here is missing "the Spirit".. I would think..
