A comprehensive investigation of the Qur'an, Bible, Islam and Christianity, revealing harmony between the principal teachings of the Books, but disharmony between the religious traditions. Suppose the Qur'an taught that: Jesus is the Messiah who was born of the virgin Mary, taught the Gospel, healed the sick, raised the dead, was crucified, died, and was resurrected; Salvation is a gift from God to all who believe, repent and ask God's forgiveness; Muslims are to believe the Gospel and other revelation contained in the Bible, believe that Jesus is the Messiah, receive guidance from the Holy Spirit, resist the temptations from Satan, avoid the condemnation of hell, and cultivate a personal relationship with the God of Abraham. If you do not believe this, then you are welcome to join me on this investigative journey where we can examine the evidence honestly. This means that: Interpretations must be supported by the evidence; Interpretations must not damage the integrity of the evidence; Assumptions used in interpreting the evidence must be verified. In my opinion, the most important lesson from studying history is: never be afraid to re-examine the evidence in order to learn or verify the truth. We should never be afraid to critically examine claims of truth, for truth should be able to withstand rigorous scrutiny.
