I believe that there is always 'light' in any given situation if we really look for it. Sometimes it's taken time for me to find that ray of sunshine (or flicker) but when I have, it's been so healing.
I believe God is the light and His light will never extinguish - you just have to open your heart a little and then He will come flooding in and light up your life.
Jesus once again addressed them:
I am the world's Light. No one who follows me stumbles around in the darkness. I provide plenty of light to live in.
John 8:12 MSG
Don't stay in the dark when you can be in the light...
