Mark 8:23-25 (NIV)
He took the blind man by the hand and led him outside the village. When he had spit on the man’s eyes and put his hands on him, Jesus asked, “Do you see anything?”  He looked up and said, “I see people; they look like trees walking around.”  Once more Jesus put his hands on the man’s eyes. Then his eyes were opened, his sight was restored, and he saw everything clearly.
His sight restored.
There are modern stories about people born blind who, when they are restored to sight, struggle with the relationship between the words for things in the dark and the words for things in the light.
What I mean of course, is that an apple you smell and feel and eat is not always recognizable as a red or yellow fruit with a smooth skin and a core.
These modern folk have had to strive to revise their scope of the world and it has felt dangerously unsteady. Sometimes a “safe” blindness can feel more familiar than a vertiginously new world of sight.
Jesus heals this man in two stages–he first restores the physical mechanism of sight, then he gives him the language to go with his new world.
I think that heaven will be like that–our senses broadened and restored. In fact, the Sermon on the Mount is the primer for the language of heaven.
