Do You Want to Be Healed?

In John 5, Jesus approaches a man who's been immobilized for 38 years and asks him, "Do you want to be healed?" This seems like a silly question. Isn't the answer obviously "yes?" After all, who wouldn't want to be healed? But perhaps the answer isn't as obvious as it appears. Perhaps we actually don't want to be healed after all. What might keep us from wanting healing, and what does the journey of healing look like?
