Reference text: Luke 18:35-43
Jesus appears to ask a question with an obvious answer.
When Jesus heard him, he stopped and ordered that the man be brought to him. As the man came near, Jesus asked him, “What do you want me to do for you?” “Lord,” he said, “I want to see!”
Luke 18: 40-41 (NLT)
The man received exactly what he asked for.
And Jesus said, “All right, receive your sight! Your faith has healed you.” Instantly the man could see, and he followed Jesus, praising God. And all who saw it praised God, too.
Luke 18:42-43 (NLT)
