Reading from the Book of Matthew 24:27
Matthew 24:27 For as lightning that comes from the east is visible even in the west, so will be the coming of the Son of Man.
Jesus said that we don't have to be worried about the exact time of His coming, and we shouldn't be deceived by those making false predictions. When He comes, there will be no doubt. As lightning flashing from the east to the west, splitting the sky in a millisecond, cracking the air with flash and fire, so will His coming be.
The next time you see a bolt of lightning cleave the sky, think of it as a reminder that His coming is near.
