Sometimes it's profitable to study Judaism in order to better understand the Old Testament. Why would we want to study the Old Testament? Because the Old is fulfilled in the New. A rabbi named Yitz Grossman has an interesting site that explains some of the beliefs of Jewish people, beliefs that may be helpful for you.
Do you recall the account of Moses and the Israelites' deliverance from Egypt's slavery? There's a lot to the story, from Israel's perspective, that I'm not sure that we, as Christians, totally "get". The article, "Interesting Torah", places a little different insight into the heavenly manna and Israel's hunger for more of the Torah. Pretty interesting information, I thought.
If you find that Yitz Grossman has something relevant to say, you might like to visit one of his other sites: Yitz Grossman Humor and Yitz Grossman Inc. of Lawrence New York.
By way of disclaimer on my part, I am not suggesting that you leave Christianity and migrate over to Judaism. What I am suggesting, however, is that we have our roots in Judaism and, if we allow God to teach us, we can learn lots about those roots from the rabbis who know much about them.
