At the most fundamental level, the conflict between the different worldviews isn’t about what sort of rules to follow. The Muslim wants us to follow Sharia, an extensive set of rules that condition everything from the relationship between men and women (the wife may be “beat lightly”) to finance. The Jew wants us to follow a moral code based on the Ten Commandments, the Christian the moral code springing from the same source in the laws Christ laid down. The Atheist wants us to follow the laws laid down by nature, in the ultimate extreme the survival of the fittest (only applied at a societal or species level).
But this focus on external realities, the laws each group would have us follow, fails to grasp the root question we really need to answer. What type of person does each system want to produce? Of course, you can’t say one group is “right,” or “wrong,” on this matter except from within the worldview itself. But considering what the god of each worldview wants helps us evaluate, understand, and —ultimately— choose.
Within Islam, what does Allah want? The word “Islam,” means, “to submit.” This is the root of all Islamic thought on Allah —he wants men to submit. Allah is not regulated by his nature, for he has no attributes; his only true existence is in his will. Therefore the only thing a Muslim can do to to please Allah is submit. Women submitting to men, infidels submitting to Muslims, governments submitting to religious leaders —Islam values submission.
Atheism claims to have no god, although it does have faith. The faith of atheism is in the ability of random chance to create order, and for the species to survive through ruthless competition with other species. Atheism values strength and survival above all else.
What does Yahweh, the God of the Bible want?
I appeal to you therefore, brothers, by the mercies of God, to present your bodies as a living sacrifice, holy and acceptable to God, which is your spiritual worship. Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect. -Romans 12:1-2
What Yahweh really wants is transformed people. God wants his followers to become more like him over time through their Christian walk. God wants his followers to grow up, to be mature, to govern their desires through self control, so that external controls are not needed. Yahweh wants his followers to become adults in his kingdom.
People often think of Christian morality as a kind of bargain in which God says, ‘If you keep a lot of rules I’ll reward you, and if you don’t I’ll do the other thing.’ I do not think that is the best way of looking at it. I would much rather say that every time you make a choice you are turning the central part of you, the part of you that chooses, into something a little different from what it was before. And taking your life as a whole, with all your innumerable choices, all your life long you are slowly turning this central thing either into a heavenly creature or into a hellish creature: either into a creature that is in harmony with God, and with other creatures, and with itself, or else into one that is in a state of war and hatred with God, and with its fellow-creatures, and with itself. We might think that God wanted simply obedience to a set of rules: whereas He really wants people of a particular sort. -C.S. Lewis, Mere Christianity
The choices offered by the three couldn’t be more stark, or more revealing.
