After some discussion, the conferees had to agree. The notion of God's love coming to us free of charge, no strings attached, seems to go against every instinct of humanity. The Buddhist eight-fold path, the Hindu doctrine of karma, the Jewish covenant, and the Muslim code of law -- each of these offers a way to earn approval. Only Christianity dares to make God's love unconditional.
Aware of our inbuilt resistance to grace, Jesus talked about it often. He described a world suffused with God's grace: where the sun shines on people good and bad; where birds gather seeds gratis, neither plowing nor harvesting to earn them; where untended wildflowers burst into bloom on the rocky hillsides. Like a visitor from a foreign country who notices what the natives overlook, Jesus saw grace everywhere. Yet he never analyzed or defined grace, and almost never used the word. Instead, he communicated grace through stories we know as parables.
