Two possible explanations to her statement. One, there was more to their conversation than the author recorded here, personal information we don't need to know. Two the revelation of her five husbands overwhelmed her and felt as if it was everything she had ever done. Either way she was convinced beyond conviction.
Jesus provides us with a discourse on the meaning of true worship. For those that believe that all paths lead to God any form of worship is suitable. Jesus says that one must worship the Father in Spirit and truth. What is true about worship if is not done in the Spirit (note: not in a spirit)? To be of the Spirit one must be born again. To be born again one must believe that Jesus is Son of God, the Christ. The Spirit cannot be forged or approximated or imagined any other way. It is the difference between believing in a god and believing God, that what He says and what He is and what He seeks for us to be is all we need consider. Some would say that that is simply too narrow; open minded is easy only for those who wish to remain uncommitted!
