The topic chosen for this book is very challenging it requires vast knowledge of both the Holy Scriptures of Christianity and Islam as 70% of world’s population belongs to these two major religions. Hence a scientific indepth analysis is needed to come to a conclusion: The comparative study will be based on the following criteria : 1. Historical background 2. Comparison of honoured personalities of both Jesus and Prophet Muhammed (Peace be upon them) 3. Analysis of both Scriptures in terms of moral and social upliftment, the concept of life after death, the concept of heaven, hell and resurrection etc. 4. The Bible or Qur’an -- which is closer to Modern Science? 5. Conclusion whether the Qur’an is Copid from the Bible or the Word of God (the Creator)? Unless we purposefully study the Scriptures and Holy Books of other religions, we ourselves stand exposed to the dangers lurking ahead. The various systems of ethics, philosophy and religion are in fact a record of the vast divergence of views on such vital questions such as : Is there a God of the universe and, if so, is He the only One or are there many gods? What is the nature of the relationship between God and human being? Has He made any arrangements for guiding humanity or not? Is man answerable to God or not? Is there an ultimate aim for man’s creation and should man keep it in view throughout his life for salvation? Though the concept of one Creator is common in all religions however most religions adopted Hero-worship or idol-worship as intermediary to which the Creator is against to accept such worship as given in the Holy Bible, Deut. 12:2-4. showing God’s ordinance to destroy completely all the pagan shrines to hew down the idols of their gods and blot out their names. As the Bible treats Old Testament as a record of God’s covenant with mankind and the implications of the covenant on human life in society and God’s expectation from humanity in response. I therefore request my readers to come to their own conclusion after reading this book and find for themselves which way to follow to achieve salvation. The life of man has a purpose to serve and a goal to achieve, this goal is the “Life Hereafter”(Eternal Life). For, it is unthinkable that man should be created just to live for a few years and then get completely annihilated like the animal world. I pray to Allah (God Almighty) to bless my effort to convey His message to my fellow human beings in order to save them from hell fire as this would be my key to salvation. As Jesus Christ (Pbuh) said: “Love your God and Love your neighbour” and I feel my neighbour is the whole community of mankind.
