Dr. Peale says we all need to know that amidst the trials of this life, God is very close and we can always talk to Him. NVP shares the story about a light in an old bracket in his house that he had never seen on. So he turned it on and it lit. If you can turn on a light that has been neglected for many years just by turning a screw, you can turn God on in your life by the turning of a thought.
