Where does morality come from? How do we judge if an action is moral or immoral? Who sets the standard for what is right and what is wrong? There are some people who believe that you can't impose your standard of right and wrong on another culture. It's cultural imperialism to think that anyone has the moral authority to tell another culture or another person that the way they live is wrong. Moral standards are relative. Yet, if you ask these people if there are others out there in the world doing abhorent evil right now, they would say of course there are! But by agreeing there is evil in the world, then they've contradicted their own stated belief that one cannot judge another. How can we insist that we cannot judge another culture or person and still believe there is evil in the world? If one tribal group decides they need to get rid of a neighbouring tribal group for no reason other than the colour of their skin, can we judge them as being immoral and evil if we claim that all moral standards are relative? If we can say, yes, genocide is evil, where does this standard of morality come from?
These are some of the lines of reasoning that Timothy Keller wants people to think through in his book, The Reason for God. As the pastor for the very urban Redeemer Presbyterian Church in New York City, he has met people with the most sophisticated worldviews for not believing in Christ. This book is the distillation of the wisdom he applies when engaging people across many fronts: logic, science, culture, art, philosophy, and religion.
The main point he espouses is we need to get people to think through their worldviews and follow them to their logical conclusions. What most people will find is that their worldviews don't hold up to close scrutiny or people don't actually subscribe to the worldview they profess and they are simply living in denial or self-imposed blindness regarding the truth about life, the universe and God.
Going back to the example of who gets to set moral standards, Keller gently prods people to think through the question of who has the right to set morals. Is it the majority that decides? That sounds good but what if the majority decides that a minority race needs to be exterminated? Or if no one can set moral standards, then the world may as well descend into chaos for no one rightly can call anyone else evil and all actions (killing, forgiving, helping, stealing, etc.) are just as neutral as another. If we're all just a ball of cells and chemicals thrown together through cosmic chance, then no one can set a moral standard and hold anyone else to that.
But the fact is, everyone believes there are moral lines that cannot be crossed. We should not kill another human being. We should not steal from another person. It's terrible to cheat on our wives. Children deserve to be protected. These moral standards sound right. But they had to have come from somewhere or someone. Who sets the standard?
Christians have an answer of course: the one who is in charge of the universe sets the standard. The one who created the world sets the standard. That person is God.
Morality is just one angle that Keller uses. He talks about science, logic, philosophy, and art. In each of these areas, he shows the reader how each angle reveals clues to God. Each point taken alone can be rejected. But like a court case where more and more clues add up to a huge body of evidence, the overwhelming effect of following through each of these areas to their logical conclusions really presents a compelling case that God really is the creator and ruler of the universe and he does have a purpose for creation and man.
I found his tone very comforting, humble and clear. I learnt that my beliefs should affect the way I live, how I treat my wife, my kids, my colleagues and how I view life. If my beliefs don't affect how I live, I can't say that I believe them at all. And my most important belief is in who I trust has the answers to life and the meaning of life. It's also not about how strong my faith is but in whom I put my faith in. Keller explains it thus:
The faith that changes the life and connects to God is best conveyed by the word "trust". Imagine you are on a high cliff and you lose you footing and begin to fall. Just beside you as you fall is a branch sticking out of the very edge of the cliff. It is your only hope and it is more than strong enough to support your weight. How can it save you? If your mind is filled with intellectual certainty that the branch can support you, but you don't actually reach out and grab it, you are lost. If your mind is instead filled with doubts and uncertainty that the branch can hold you, but you reach out and grab it anyway, you will be saved. Why? It is not the strength of your faith but the object of your faith that actually saves you. Strong faith in a weak branch is fatally inferior to weak faith in a strong branch.
The object of our faith is more important than the strength of my faith. I really do need to believe in the right thing. But more than belief, I need to let my faith affect my life. As Keller puts it, "There [is] no use just saying you believe in Jesus unless you let that change your life and affect your view of everything."
Keller quotes these powerful words from C.S. Lewis:
The Christian way is different—both harder and easier. Christ says, "Give me ALL. I don't want just this much of your time and this much of your money and this much of your work—so that your natural self can have the rest. I want you. Not your things. I have come not to torture your natural self... I will give you a new self instead. Hand over the whole natural self—ALL the desires, not just the ones you think wicked but the ones you think innocent—the whole outfit. I will give you a new self instead."
I want to let Jesus affect every part of my life. I want to follow him all the days of my life. I want to echo Peter's response to Jesus' question after his hard teaching about being the Bread of Life: “Do you want to go away as well?”
Simon Peter answered him, “Lord, to whom shall we go? You have the words of eternal life, and we have believed, and have come to know, that you are the Holy One of God.” (John 6:68-69)
