the healing at the Pool on the Sabbath

Jesus said to him, "Get up, take up your bed, and walk." And at once the man was healed, and he took up his bed and walked. Now that day was the Sabbath. - John 5:8-9

Where is the man’s will and choice in this narrative? Where is there any evidence in this story that testifies to this invalid making a choice to let Jesus heal him?

This miracle is a glorious affirmation of God’s sovereignty and grace in saving invalids with no power to save ourselves. This man had no idea who he was speaking to. Jesus commanded him, the man was healed and he took up his bed and walked.
