"Can you think of something that might happen today when you should be ready to ask, 'What would Jesus do?'"
I think I'd get an answer- though not necessarily the right one. I have a lot more to learn about Christ before I'd have anything approaching a right answer- but having him close at hand, and in your thoughts, is a lot more likely to prompt you to take a good action. Even if it isn't necessarily the one he would have done- it means you're trying to be like him, take his teachings into consideration in any situation- and who knows, God may see fit to grant you the answer. Whether or not I'd be able to carry it out is a different story, but hopefully.
