God is a master of signage. Here is what Jesus said in Matthew 16:2, “When it is evening you say, ‘It will be clear weather, because the sky is red.’ And in the morning, ‘There will be a storm today, because the sky is red and threatening.’” In English we say, “Red sky at night is a sailor’s delight; red sky at morning, good sailors take warning.” God puts up a brightly lit sign every morning and evening so we can prepare for the weather He is sending. He also lights up a sign for certain generations in world history.
