Christianity's radical idea
For God so loved the world that he gave his only-begotten Son, that whoever believes in him shall not perish but have eternal life. (John 3:16-21) In this passage, John introduces a theme he comes back to again and again in his Gospel and his letters : love . Here is right where it starts: God loved the world . The word there is cosmos , and it means that God loves the whole creation and everyone in it. He demonstrates his love in a very particular way: he gave his only-begotten Son . This is the good news.
