So you want to join a club that wants nothing to do with God. Reform Judaism is a great place for you.
I would read up on the treads of Reform Judaism, attend some club functions, and see how much you enjoy being involved. Once you have seen enough radically different takes of Judaism, find a rabbis you like and start the initiation process.
But first, let's get some history on Reform Judaism from Judaism Online
http://www.simpletoremember.com/articles/a/reformconservativeorthodox/
Reform Judaism started at Pittsburgh conference of Reform leaders in 1885 and was lead by
Dr. Kaufman Kohler told the assembly:
“We consider their [the Holy scripture’s] composition, their arrangements and their entire contents as the work of men, betraying in their conceptions of the world shortcomings of their age...
"I do not for a moment hesitate to say it right here and in the face of the entire Jewish world that… circumcision is a barbarous cruelty which disfigures and disgraces our ancestral heirloom...
"I can no longer accept the fanciful and twisted syllogisms of Talmudic law as binding for us… I think, if anywhere, here we ought to have the courage to emancipate ourselves from the thralldom of Rabbinical legality.
With few modifications, the conference unanimously adopted Dr. Kohler’s proposed Pittsburg Platform."
The same article fast forwards to 1972:
"A survey commissioned that year by the Central Conference of American [Reform] Rabbis, reported that “...ninety-percent classified their faith with terms like: “Agnostic;” “Atheist;” “Bahai in spirit, Judaic in practice;” “Polydoxist;” “Religious Existentialist;” and “Theological Humanist.""
As you can tell from how Reform rabbis classified their faith, there is a great deal of diversity among Jews so it is impossible to walk into one and know what their focus is.
In fact, when answering the question, "Who is a Jew?" Judaism 101 states,
http://www.jewfaq.org/whoisjew.htm
"It is important to note that being a Jew has nothing to do with what you believe or what you do...a person born to a Jewish mother who is an atheist and never practices the Jewish religion is still a Jew, even in the eyes of the ultra-Orthodox."
When you never have to practice the Jewish religion, what you have is a club and you need to get to know your club to know what is their focus
Instead of Reform Judaism, you might want to explore Flexidox:
http://judaism.about.com/od/flexidox/Flexidox_Judaism.htm
In 2003 Rabbi Gershon Winkler coined the term Flexidox as a corrective to Orthodoxy, "reflecting its original intent and spirit as opposed to its otherwise superficial extremities." A flexidox Jew may think the Torah was written by people, but keep kosher and the Sabbath laws. He or she may pray in an Orthodox synagogue, but support equal synagogue roles for women and the ordination of gay rabbis.
As you can see in this paragraph as well, you can believe that just people wrote everything about God without being God inspired...and still keep kosher and the Sabbath laws as if they were inspired.
Hope this helps
Side note, Messianic Jews are not non-Messianic Jews because of their belief that God can still speak and act as all Jewish scriptures teach.
Since Judaism 101 clearly states, " being a Jew has nothing to do with what you believe or what you do" to the point ".a person born to a Jewish mother who is an atheist and never practices the Jewish religion is still a Jew", it is completely irrational to say that Messianics can't be Jews because of their belief.
Aravah will disagree with the definition but is completely helpless to improve it to something she likes without offending half of the Jewish population.
Seriously, you can't say that a polar bear isn't a bear because the black bear and brown bear voted and said you can't be a bear and have a white coat...but these are the silly things they teach you if you want to be a part of their club. It is also why it usually takes a year and a half...they have to condition you to have these knee jerk, illogical responses.
So Aravah, tell us one more time why you converted to Reform Judaism when all paths lead to heaven and other non-Messianic Jews reject your conversion.
