Book excerpt: Jesus worked hard to make the world beautiful. He performed miracles, told fabulous stories - all for free - and generally spent his time spreading joy and light around the world. A tiring business, as Jesus had to admit when, one day, he had trouble getting out of bed. And worse - the miracles start to go wrong! But help is at hand. 'Take the day off, Jesus, ' said the doctor. 'Relax. Have some fun!' So Jesus had some fun - but was it worth it? Dad, as usual, has the answer!
