Invisible Light.

"Even darkness is not dark to you, the night is as bright as the day, for darkness is as light to you."  Psalm 139:12 (NRSV)

The spectrum represents the range of light visible to our human eyes.

But there are forms of radiation outside of this visible spectrum that can be seen by some animals.

Infra-red, ultra-violet etc..

This is invisible light.

Which to us is darkness.

But it is bright as day to the Lord.
