“The heart of the unique message of the Bible is that the transcendent, immortal God came to earth himself and became weak, vulnerable to suffering and death. He did this all for us—all to atone for our sin, to take the punishment we deserved. If it is true, it is the most astonishing and radical act of self-giving and loving sacrifice that can be imagined. There could be no stronger basis and dynamic motivation for the revolutionary Christian ethical concepts that attract us. What made Christian ethics unique was not that Jesus and the early Christians were such nice people doing all these nice things to make the world a nice place to live. These ideas never occurred to anyone as making sense until they came to understand the Christian message about the nature of ultimate reality—and that message is summarized in what the Bible calls “the gospel.”
