George Wood was a superintendent of the US Assemblies of God. He shared the following story in a Preaching Today sermon:

When I was a boy, my sister left our home in Pennsylvania, and traveled to Central Bible College. She had a lifelong problem with her eyesight. She had 20 percent vision in one eye and 50 percent vision in the other, and wore thick, Coke-bottle glasses.

During a fall revival at Central Bible College, she had been praying at the altar and saw a vision of Jesus on the cross. She felt a voice, saying to her, "Doris, take off your glasses." In those years, if you wore glasses, you were prayed for on a regular basis—that you would be healed. My sister had had enough of that, so she said, "No."

Again, she felt the voice say to her, "Doris, take off your glasses."

Again, her response was, "No."

A third time, while she was having the vision of Jesus on the cross, she felt this voice say to her, "Doris, take off your glasses." She sensed it might be the Lord, so she prayed, "Lord, if I take these glasses off, I don't want to ever put them on again."

The vision disappeared, she opened her eyes, and she had perfect sight. It's been 50 years. She has never put on a pair of glasses to this day.
