The Law of Diminishing Return

March 5, 2009

C.S. Lewis states the principle this way, “An ever increasing craving for an ever diminishing pleasure….”* The law of diminishing return is observable in sinful behavior. 

We’ve all felt the euphoria of physical exercise or work. It is a wonderful feeling – a God given pleasure. When we chase, however, an artificial euphoria through drugs and alcohol, painful consequences occur. Intoxication or a drug induced high can cause people to engage in risky behavior that harms the user or some innocent bystander.

When these behaviors become addictive, relationships are harmed. Work is harmed. Even the basics of taking care of ourselves are harmed. The euphoria may actually become harder to get, and the pursuit of the false euphoria does physical damage. Ever taken a look at the before and after pictures of a meth user?

The same thing can be said for sexual desire. Sexual desire, after all, is God’s idea. He made us male and female. Within marriage it is part of a wonderful bond that allows two people to grow in a lasting relationship. But pervert this desire into lust, and it works against relationship and a lasting bond. The complaint that it objectifies women (or men, for that matter) is a legitimate complaint.

Allow lust to lead to pornography, and it can degenerate even further. I rely on those who have written about this world. It is too dangerous a world to allow idle curiosity to visit, because it can enslave the visitor. Like most men in our culture, I have been on the edges of this world enough to realize it has an allure. The sirens’ song must be ignored, because the possibility of shipwreck is real. I’ve talked with enough men and women who have struggled with it in their relationship to know pornography has harmful effects.

The softer porn is closer to the natural sexual desire. But like a drug that can only satisfy with ever increasing doses, it can lead people to even more twisted views of sexuality: sexuality with violence, bestiality, and worst of all – child pornography. Even when people don’t make the descent into ever increasing levels of perversity; it still robs people of God’s intention for sexuality. In some cases, it may rob its victim of the possibility of real sexuality. Pornography promises what it cannot deliver – the human longing for intimacy. It is relationship destroying, not relationship building.

Isn’t it interesting that the law of diminishing return is observable? It seems to suggest that we live in a moral universe after all.

Eyes to See

February 6, 2009

Does everyone have the same moral sensitivity? Raising the question is to answer it. Disagreements over morality exist. What one person may find acceptable is reprehensible to another. The question isn’t whether I do things that I think are wrong. All of us experience that. The question is actually over defining right and wrong. In his book  Mere Christianity, C.S. Lewis observed:

When a man is getting better, he understands more and more clearly the evil that is still left in him. When a man is getting worse, he understands his own badness less and less. A moderately bad man knows he is not very good: a thoroughly bad man thinks he is all right.*

Isaiah represents a good test case. When confronted with the Holy One of Israel, he cried out, “Woe is me! For I am lost; for I am a man of unclean lips, and I dwell in the midst of a people of unclean lips; for my eyes have seen the King, the Lord of hosts” (Isaiah 6:5, ESV)! When God explains his purpose as a prophet, He turns the tables and actually uses result language:

And he said, “Go, and say to this people: ” ‘Keep on hearing, but do not understand; keep on seeing, but do not perceive.’ Make the heart of this people dull, and their ears heavy, and blind their eyes; lest they see with their eyes, and hear with their ears, and understand with their hearts, and turn and be healed.” Isaiah 6:9-10, ESV

God really did want His people to repent, and Isaiah’s task was a call to repentance (see Jeremiah 18:7-10). The switching of purpose for result was cautionary for Isaiah. It was going to be no easy task. He was living among a people who were calling evil good and good evil (Isaiah 5:20). Although Isaiah was morally sensitive, many of his listeners were not.

Conscience is the faculty of moral sensitivity, so guard your conscience. A healthy conscience helps us to choose good and avoid evil. A working conscience may even lead us to the Good—God. But wrong choices can silence the conscience’s alarm. Hit this snooze button enough times, and the alarm may no longer work. If you allow your conscience to become insensitive, dull, and hardened, then in the moral realm, you will no longer have eyes to see.
