There are time when we walk into dark tunnels.
We look round for our light, our guide.
The pin-prick of light at the end of the tunnel.
The light guiding us home.
Assurance we can see.
But we see no light.
We see not because it is with us.
At our side, supporting us.
An invisibly infinite support for us.
It carries us through.
Back to safety.
Into the light of the sun.
We realise how lovely it is.
It warms us as well as letting us see.
