"Therefore the world does not know us, because it did not know Him." (1 John 3:1)

A number of years ago a story appeared which told of a man who picked up a beautiful rock from a North Carolina stream bed and used it as his cabin doorstop. Years later a geologist who was hiking in the area stopped at the cabin and noticed the doorstop, which he immediately recognized as a huge lump of gold. In fact, it proved to be one of the largest gold nuggets ever found east of the Rockies.

Likewise, the true children of God are in the world, but people of the world do not recognize them because they do not know God.
