Same as it is Different

Besides just obviously being old religious scriptures that teach the word of god, both the new testament and Quran are similar in other ways. I believe that since Islam and Christianity are both monotheistic and have biblical ties to each other, both higher powers (God) in each religion are the same God. Let's look at purified life in the Quran and New Testament. The Quran states that "Whoever does good, whether male or female, and is a believer, we shall certainly make him live a good life." (Nahl, 97) and in the Bible it states "For here we do not have an enduring city, but we are looking for the city that is to come" (Hebrew 13/14). Both believe in some form of eternal life or, purified life, and that after life is the same (my opinion).
