"[Lord] I believe; help my unbelief!" Mk 9:24
What struck me when I watched this was one thing: obedience.
The doctor was obedient to God's command even when it made no rational sense.
Even when it was inconvenient and even when it would cause embarrassment.
Even when he had no faith that anything would happen.
"For truly, I say to you, if you have faith like a grain of mustard seed, you will say to this mountain,
‘Move from here to there,’ and it will move, and nothing will be impossible for you.” Mt 17:20
