No, I am not saying that there are just similar concepts in both the Qur'an and the Bible. I am saying that there are passages in the Bible that are either close to being identical, paraphrased or alluded to in the Qur'an. This is not a majority of verses, but they are there.

Now, when it comes to the Bible, the concepts within seem to draw very heavily on older religions. I would do some research on Mithra and even Horus. It is interesting how many of these ancient gods died for the sins of mankind, were said to have been born of a virgin, were put to death and were resurrected and some were even said to have been born (incarnated) on the winter solstice. The parallels are simply too much to ignore (imo).
