He is a spirit, and the God and father of our Lord Jesus Christ

John 4:23-24
23    But the hour cometh, and now is, when the true worshippers shall worship the Father in spirit and in truth: for the Father seeketh such to worship him.
24    God is a Spirit: and they that worship him must worship him in spirit and in truth.

The scripture declares that we are to worship God in spirit and in truth, not by bowing to statues or other material elements. By worshipping objects we make them our gods. The true God is a spirit and we can only worship him in truth by way of the spirit he gives us.

48    Howbeit the most High dwelleth not in temples made with hands; as saith the prophet,

50    Hath not my hand made all these things?

As the above verses indicate Gods nature is not identical to mans nature.  Gods true nature is: invisible; immortal; all knowing; all seeing, etc., whereas man is: visible; mortal; partially knowing and seeing, etc.  These few verses represent only a few of the personal qualities of God the Father and creator of all things.
