The claim is made that God the Father is spirit, and the words of Christ to the Samaritan woman at the well are used to back this up.

I understand the verse but I don't understand what spirit is. Can anyone provide any Biblical verses to show what Spirit is? And don't tell me what Christ told the apostles after his resurrection. I don't need to know what a spirit is not. I want to know what a spirit is.

Anyone?
