Here's a good distinction he makes between morals and values:
"I feel that another aspect of this reader's question deserves a response. He asked "to what extent, then, can we impose Christian values by law?" Here I think we need to pause to distinguish between values and morals. It used to be that we spoke of morals--truths that were applicable to all people. Societal morals were built upon a Christian foundation so that society widely accepted that homosexuality was wrong, that abortion was forbidden, that truth was a virtue, and so on. These morals stood above society, giving structure and imposing themselves on all people. But in recent decades, coasting in alongside a naturalistic worldview, morals have been diminished and have been replaced by values. Where morals are absolute, values are inherently subjective. Each of us may have our own sets of values. Society dictates that you are required to respect my values while I am required to respect yours.He concludes this way:
So to what extent can we impose Christian values? Well, in a sense we do not seek to impose Christian values at all. Instead, we seek to impose Christian morals. We affirm that the Scripture gives us absolute standards of right and wrong and we seek to live within these boundaries. Again, these morals stand over and above us and call us all to obedience. They are vertical rather than horizontal. So we do not face our society with an attitude implying that we both hold to values and I hope that you will accept mine. Instead, we face society with the conviction that God's morals are good and absolute. We can impose these morals on others without fear. Were a national leader to find himself in a position of being able to eradicate abortion, he could do so from a moral standpoint and do it without regret or hesitation. In such a case he has no need to concern himself with another person's subjective values."
"Abortion is so awful, so despicable, so abhorrent that I have to think it will, indeed, be abolished some day. It is my hope and even my conviction that we will someday regard it as we now regard slavery. We will shake our heads and wonder how we could ever have lived in such a society. Children will learn in school of society's ambivalence to so great an evil and express proper shock and disgust. And I hope and pray that Christians will lead this fight and ascribe all glory to God when the battle is finally won."Read all of it
