“Martin Luther once said that the gospel is like a caged lion that does not need to be defended — only released. Indeed the gospel is the power of God for salvation (Rom. 1:16; 1 Cor. 1:18). When it is at work in the words, works, and lives of God’s people, it will accomplish its purposes. But the gospel is ‘caged’ when it is accommodated to the story of humanism. Only when the gospel is set free from its captivity to the dominant cultural story will the church be equipped for its comprehensive mission in Western culture.”
