Just for a moment, I want you to close your eyes and imagine that you are blind. Now, let's complete a few basic tasks, like separating medications, using the right button on a microwave oven or knowing which side of the street to catch the bus. Think of all the questions you might have because you can't see.

There's a new non-profit app out that allows sighted people to "lend their eyes" to those with visual impairments through video chat. Simply put, it's remarkable. The "Be My Eyes" app was developed by a visually impaired man in Denmark. It connects blind people to sighted volunteers through video chat. The volunteer can answer questions because they can see the blind person's surroundings using their phone's camera.

The other day, "Be My Eyes' app user connected with a young man who wanted to know the expiration date of the milk in his refrigerator. The visually impaired man positioned his phone's camera to the top shelf. Looking at the image of the milk carton on my phone, the app user said, 'I wouldn't drink that if I were you.'"

Preaching Angles: Jesus calls us to be the light of the world to people who are lost in spiritual darkness. Our light should shine out so that others can enter his marvelous light.
