A crack opening in my Window

My window has a crack opening
For a small ray of right to peep through
To lighten up dark chambers of heart

As You had shone through opening
Gone are those darkest days
when I could feel nothing
I was grasping in the dark and
heart yearning for thine light

Alas some dark corners still remain to be illuminated
With unknown cobwebs lurking there

I am yearning for your grace to shine
For My window to open far and wide
Small ray of light to turn into flood of light
Shining  every nook and corner
Illumminating my heart brighter and brighter
