Imagine being paralyzed lying barely out of reach of a pool that you believed would heal you for 38 years.
38 years you stare at your destiny.
38 years you see man after man go into this pool and be healed.
38 years you lay there as your body is wasting away.
38 years you hope.
Then one day a man comes up to you and ask you if you want to be healed.
What kind of question is that. Of course you want to be healed. Of course you want to experience what it would be like to walk again. Of course you want to experience life.
All you need is someone to put you into the pool. All you need is someone to come along and grant you your hope.
And then the man says "Get up, take your bed, and walk."
Get up now?!?!
And at once you were healed, at once you took your bed, at once you walked.
