How can they understand?

The light shines in the darkness, but the darkness has not understood it.
There came a man who was sent from God; his name was John. He came as a witness to testify concerning that light, so that through him all men might believe. He himself was not the light; he came only as a witness to the light. The true light that gives light to every man was coming into the world.

John 1

Your friends, your co-workers, your classmates & your family....maybe they are in the dark? You are either in the light or the dark.....IF you or they are in the DARK they DO NOT UNDERSTAND the LIGHT.

It is up to you.....YOU ARE THE LIGHT!
