Funny, you make the quran sound like the words written of man.
God is Spirit. His book the Bible is written in the same Spirit. It has to be understood by the Spirit which only comes from God and is the nature of God. But since you don't have the Spirit or the understanding of the Spirit you cannot understand the Bible, but don't fret cause the angel of light wrote you a book called the quran, written in the form of this world just for your worldly understanding.
