"Then I looked when the Lamb opened the sixth seal, and a huge earthquake took place; the sun became as black as sackcloth made of hair, and the full moon became blood red" (Rev. 6:12 NET).
Half Banana, perhaps this will help you to consider such a sweeping statement. Above photo is of the sun, using a zoom lens, polaroid and light density filter. The light density filter gradually removes the light as you turn it from maximum to minimum. As you remove the light, above photo is what you end up with. Obviously above is not the sun. Question is: Where is the sun? Here I refer you to above scripture as explanation. Not bad for a prediction made over two thousand years ago. Go figure.
