Jesus healed a blind man, but it was difficult and took two tries. When Jesus is healing us, we need to have patience. Healing takes time.
Based on Mark 8:22-26:
Jesus and his disciples came to Bethsaida. Some people brought a blind man to him and begged him to touch him. He took the blind man by the hand and led him out of the village; and when he had put saliva on his eyes and laid his hands on him, he asked him, ‘Can you see anything?’ And the man looked up and said, ‘I can see people, but they look like trees, walking.’ Then Jesus laid his hands on his eyes again; and he looked intently and his sight was restored, and he saw everything clearly. Then he sent him away to his home, saying, ‘Do not even go into the village.’
