Increasingly, our culture has adopted the religion of secular humanism, the idea that humanity can build a good life without God. How can Christians maintain a relevant witness in this kind of world? First, we must understand it. Secularism is not life without God; it is life with different gods. What are they? When people worship these gods, what are the results? Second, we need to do a gut check: Are we wearing a label or living the life? When we embrace radical discipleship, the Lord can use us as a living picture of the Gospel, a flesh-and-blood display of his saving work. When our lives are centered on God’s glory, we give people a chance to see what it looks like to live for something much bigger than the idols of our world. This is our best hope for reaching a people consumed by radical secularism.
