Sparrows and Salvation

Luke 12
6 Are not five sparrows sold for two farthings, and not one of them is forgotten before God?
7 But even the very hairs of your head are all numbered. Fear not therefore: ye are of more value than many sparrows.

Comfort
As much as I, in my darker moments, fear God, I do not worry about my salvation. I always remember:

His eye is on the sparrow
and I know he watches me.
