gentiles - Conversion: If G-d really wanted me to be a Jew (and observe mitzvot), why was I not born into a Jewish family

This question pertains to the issue of conversion, and if it makes sense in the Jewish context of some people being Chosen specifically by God.

Before beginning, this poster is aware of the long, and serious process of conversion, the commitment it requires, and the eternal nature of it. I am also aware that non-Jews can receive a share of the world to come, and that they can have a perfectly fine (albeit, less developed) relationship with G-d by following the Noachide laws and being a good, moral human being. This is a general or hypothetical question, but I look forward to your answers!

I have long been fascinated by Judaism, and I even like to think that I know more about Judaism than some Jews. I have always felt a strong connection to the God of Abraham, Isaac, and Jacob and I believe I have felt his presence in my life as a non-Jew. However, I have long wanted to convert because I believe it would make my relationship with G-d closer, I love Jewish culture, and because I want to be a part of the Jewish community.

However, I am having trouble with some of the fundamental aspects of whether or not conversion makes sense in a religion where followers are, by and large (with exceptions for Abraham and so on), "Chosen" by G-d.

Therefore, my dilemma is essentially this:

Though I feel deeply like I have a Jewish soul, and I love G-d, and I wish to be a full member of the Jewish tradition...I am stuck thinking that I should not convert because, if G-d had wanted me to have a Jewish soul, wouldn't He have had me born into a Jewish family?

On some level, I have to ask myself if converting to Judaism would not almost be a rejection of G-d's plan for my life. Would I not be second guessing Him, if I was born into a non-Jewish family? Does not G-d direct who were are born into, and does He instead wish me to live as a righteous Gentile? Who is the pot to question the potter?

I would appreciate any insights you can share on this, and any real-life examples or sources to help me understand if conversion is the right thing to do.
