Much has been written about the three hours of darkness (Matthew 27:45), much of which is not warranted by any careful spiritual attention to the story itself. Many years ago, it was argued that the darkness was that of the sun's eclipse. But that is entirely impossible, for Passover was always held at full moon, when there could be no eclipse of the sun.
The darkness has been described as nature's sympathy with the suffering of the Lord, but that is a pagan conception of nature, a conception of nature as having some consciousness apart from God and out of harmony with His work.
It has been said that the darkness was brought about by an act of God and was expressive of His sympathy with His Son. I immediately admit that that is an appealing idea and has some element of truth in it, in that we may discover the overruling of His government; but to declare that that darkness was caused by God because of His sympathy with His Son is to deny the cry of Jesus which immediately followed the darkness and referred to it. The darkness was to Him a period when He experienced whatever He may have meant by the words, "Why have you forsaken Me?"
