Those who continually refuse to acknowledge God walk into the darkness. At a certain point, God lets them go. This is a problem that can affect both Christians and non-Christians as they refuse to acknowledge Christ or neglect to thank Him. In the darkness, they can’t see. They lose the distinction between truth and error, right and wrong, and reality and make-believe. In their darkness, they begin to think darkness is light and light is darkness. We’re seeing this lack of discernment in society and churches.
