While studying the Jewish roots of Christianity a couple of things have struck me recently as interesting:
1. While the entire Bible is God's Word and was originally a "Jewish" book (written by Jews with God's inspiration), nowadays you'll note many Jews (excluding Messianic Jews of course)deny what Christians call the New Testament or New Covenant as well as Jesus as the Messiah. On the other side you have many Christians discounting the importance of the Old Testament. I believe we need both to fully understand God and develop a deeper relationship with Him. One without the other gives us an incomplete picture of our awesome Creator.
2. Currently you find Christians trying to convert Jews to "their" religion of Christianity. Sometimes in doing so they are expecting them to give up their Jewish heritage/traditions/customs/culture. However, the question in the early church (which was originally 100% Jewish) was whether Gentiles (non-Jews) could be followers of Christ and if so, did they need to convert to Judaism in order to do so.
Maybe we should think about finding the true answer somewhere in between? Seems the church over time has gone from one extreme to the other. Just my thoughts.
