In my reading this past month, I discovered that Immanuel Kant made a case for a Christian sexual ethic but without using any appeal to the Bible or theology. In "Duties Toward the Body in Respect of Sexual Impulse" (Kant, Lectures in Ethics) he argued that sex outside of marriage dishonors human dignity. He reasoned that when you ask for sex without giving your whole self to the other person in marriage ("person, body and soul, for good and ill and in every respect"), you turn the sex partner into an object, a mere means to a selfish end, instead of an end in him (or her) self. Kant's famous "categorical imperative" was that human beings should never be treated as means, but only as ends. Using only this belief, which is intuitive for many modern people, he argued that you should never have sex outside of marriage.

Some years ago I preached through the book of Proverbs, and I learned two things I hadn't known about it. First, the Proverbs only give up their meaning cumulatively. No one proverb gives you the whole picture. If one proverb says, "the morally good always have a good life" and a later proverb says, "sometimes the morally good suffer" we think it's a contradiction. That's because we think of each proverb as an individual stand-alone promise. But they are not. All the proverbs on a given subject are meant to be taken together, each one modifying the others like the parallel clauses do. One gives you information about a topic; then subsequent ones come along and answer questions raised by the first one, or they condition and nuance a more blanket statement made earlier.

The root idea of modernity is the overturning of all authority outside of the self. In the 18th century European ‘Enlightenment’ thinkers insisted that the modern person must question all tradition, revelation, and external authority by subjecting them to the supreme court of his or her own reason and intuition. We are our own moral authority. 
 

It's remarkable to read David, the Warrior-King of Israel, writing these words from Psalm 131.

My heart is not proud, O LORD, my eyes are not haughty; I do not concern myself with great matters or things too wonderful for me. But I have stilled and quieted my soul; like a weaned child with its mother, like a weaned child is my soul within me.

Some people hear me speak about the ideas importance of city ministry and think I'm saying That all Christians (at least all those missions-minded) should move into cities. But I'm not saying that. I'm saying That many more mission agencies and many more Christians ought to minister in cities than are currently doing so. Why? Because of the sheer masses of people who live there and Because of how influential cities are on Their respective societies and cultures.
