Qur’an was revealed to amend so many things in the lives of human being. If not for the Qur’an, humanity would have been left with having negative and bad picture about God. Despite the fact that condemnation of a righteous and innocent soul is clearly forbidden in the Bible (Matthew12:7, Proverbs17:15, Exodus23:7, Psalm34:22), the same believers in the Bible still believe that an Omnipotent and Merciful God MUST CURSE (Deuteronomy 21:23,Galatians 3:13) and condemn His only beloved and innocent son on the cross of Calvary in order to achieve a particular greater purpose like solving the problem of sin with humanity or rescuing the humanity from the bondage of Satan or redeeming the souls of humanity from eternal damnation. The doctrine of an only beloved and innocent son who was under the curse and condemnation of His own merciful and omnipotent Father is self contradictory and repugnant to human mind. Before the advent of Christianity, nobody would believe that such a doctrine can even exist. It is totally foreign and contradictory to our logical reasoning for God of love, mercy and justice to curse an innocent and righteous soul for any reason whatsoever. This is the reason why the message of atonement through Jesus crucifixion was a stumbling block to the Jews and foolishness to the gentiles during the lifetime of Jesus’ apostles ( 1st Corinthians 1:23). But Paul managed to write some verses to solve this problem of logical contradiction inherent in this very doctrine. Such verses are as follows: The natural man does not receive the things of the spirit, for they are foolishness to him; he cannot understand them because they are spiritually discerned (1st Corinthians 2:14). For the message of the cross is foolishness to those who are perishing (1st Corinthians 1:18). Because the foolishness of God is wiser than men, and the weakness of God is stronger than men( 1st Corinthians 1:25). This is the reason why many Christians see no logical problem again with the idea of “an innocent, beloved and righteous son who was under the curse and condemnation of his own merciful and omnipotent Father”. Therefore, base on the verses quoted above, Paul has succeeded in making the Christians to think that a spiritual religious doctrine which is completely foolish to our logical reasoning could actually be a great wisdom in the sight of God. But if Paul's assertion is really true, why would God of reason and rationality (Isaiah 1:18) ask a natural man to believe and accept a true spiritual doctrine that cannot be understood and completely foolish to his logical reasoning especially when that reasoning is the ONLY INSTRUMENT at his disposal to recognize that true spirituality in the midst of many fake spiritualities? If there is only one spirituality in the entire world of human being, then Paul may be right in his claim. But there are many spiritualities like Christianity, Islam, Hinduism, Buddhism, Judaism, Confucianism, Jainism, Zoroastrianism, Baha’ism, Taoism and Sikhism. Since each of these spiritualities is claiming to be on the right path, it is now left for any natural man to use the only instrument (his logical reasoning) given to him by God to recognize the true spirituality in the midst of many fake spiritualities. This is exactly the reason why God must design the true spirituality in such a way that all its basic and fundamental doctrine does not in conflict with the basic logical reasoning He bestowed upon a natural man. A fundamental true spiritual doctrine may support or be neutral to basic logical reasoning bestowed upon natural man, but they will never be in conflict with each other. How could true spirituality designed by God and basic logical reasoning originated from the same God be in conflict with each other? If they can be in conflict with each other, then how can a natural man decide whether to accept or reject a true spiritual faith at first instance? Have you now seen how Paul get it wrong by asserting that “the natural man does not receive the things of the spirit, for they are foolishness to him”? Is true spirituality not meant to be accepted and embraced by natural man? Now that it is foolishness to him; how is he going to accept and embrace it? To see further that Paul is wrong in his claim; suppose you are invited by a friend to accept a religious faith that is very rich in spirituality. But one of its unique and fundamental doctrines you must embrace without question is that you have to believe that God MUST commit an act of lying in order to achieve a particular greater purpose (May God be Exalted and glorified above such behavior). Now answer the following questions; 1. Would you just accept such faith because of its spiritual richness or reject it because of its foolishness to your logical reasoning? 2. Would you not ask about the actual connections that exist between that greater purpose and the act of lying that must be committed by God before the purpose can be achieved? 3. Would you not ask why All- knowing and Omnipotent God decided, at first instance, to give preference for such irrational way of lying to achieve a greater purpose over many rational ways He can design and create from His infinite knowledge and unlimited power to achieve that greater purpose? 4. Would you just accept that the way of such a lying God is higher and complex than your own way of thinking? 5. Would you just fold your arms and accept that the foolishness of such a lying God is wiser than the wisdom of all men (see 1st Corinthians 1:25 quoted above)? Now ponder over these five questions cited above and then tell me the difference between this imaginary faith which proclaim that God MUST commit an act of lying to achieve a particular greater purpose and the Christian faith which also proclaim that God MUST curse (Galatians 3:13,Deuteronomy 21:23) and condemn an innocent and righteous soul on a cross of Calvary to achieve a particular greater purpose-like solving the problem of sin with humanity or rescuing the humanity from bondage of Satan or redeeming the souls of humanity from eternal damnation. Therefore, if you reject this imaginary faith because of its foolishness to your logical reasoning, then you must also reject Christianity since the two faiths are telling us the exact opposite of what we naturally know about God through our logical reasoning. As God is naturally known to ALWAYS TELL THE TRUTH AND NEVER TO COMMIT AN ACT OF LYING for any greater purpose; He is also naturally known to ALWAYS BLESS THE INNOCENT AND RIGHTEOUS SOUL AND NEVER TO CURSE THE SAME SOUL for any greater purpose. God may allow an innocent and righteous soul to suffer for one reason or the other. But God would never "curse" an innocent and righteous soul for any reason whatsoever. It is now clear that even if there are some spiritual benefits in the inner rooms of a true faith, there is still need for the logical reasoning to take us to the main door of those inner rooms at first encounter. But as we have pointed above, the doctrine of a merciful, omnipotent and All-knowing God who cursed and condemned his only beloved and innocent son on the cross of Calvary for a particular greater purpose is totally in conflict with what we naturally know about God through our logical reasoning; yet this is one of the fundamental doctrines you must embrace wholeheartedly for you to become a serious and devoted Christian. Therefore, there is need for God to send another prophet to remove this negative and bad picture of God from the minds of the general humanity. This is one of the many reasons why Qur’an was revealed by God to Prophet Muhammad (pbuh). In the Holy Qur’an, God removed this negative and bad impression from the minds of the people by declaring that, in a miraculous way, Jesus escaped death on the cross (Qur’an 4:157-158). In this way, the "curse of God" associated with any one that is crucified and died on a cross according to the Jewish law (Deuteronomy 21:23, Galatians 3:13) was removed from the head of our beloved and innocent prophet called Jesus Christ(peace be upon him). This is exactly in line with the prayer of Jesus to God in the garden of Gethsemane when he asked for this “cup of condemnation” to be taken away from him in THREE consecutive times as stated clearly in Matthew 26:36-44. Therefore, an illogical idea of God cursing an innocent and a righteous soul on a cross in order to achieve a particular greater purpose is far away from the truth. The fact that the Holy Qur’an is the only religious book on earth that remove this negative and bad impression about God from the minds of the general humanity is a very great indicator that the book could never have come from no other person except God Himself.

How far can logical reasoning go? Can it go as far as denying the very existence of God?

I have noted a particular attribute of God the Quran has made prominent that is God is incomprehensible. That God's mind is a billion light years away from man's and there is hardly a common ground of understanding between both. Now if God's truest intention cannot be known to man due to his incomprehensible nature then your entire analysis would not worth a dime.

Furthermore what are the concepts of justice and mercy to a being without responsibility to any one. Why would God feel guilt if he is unjust to us humans? I don't see how he would.
