John Wesley on Matthew 27:45

From the sixth hour, there was darkness over all the earth unto the ninth hour - Insomuch, that even a heathen philosopher seeing it, and knowing it could not be a natural eclipse, because it was at the time of the full moon, and continued three hours together, cried out, "Either the God of nature suffers, or the frame of the world is dissolved." By this darkness God testified his abhorrence of the wickedness which was then committing. It likewise intimated Christ's sore conflicts with the Divine justice, and with all the powers of darkness.
