Jesus said, “The kingdom of heaven is also like a fishing net thrown into the sea. It collects fish of every kind. When it is full, the fishermen pull it up to the beach and sit down to sort out the fish. They put the good fish into baskets and throw the bad ones away.
That’s exactly how it will be at the end of time. The angels will come and sort the people. They will separate the wicked ones from the righteous ones. The wicked ones will be thrown into the flaming furnace, where there will be crying and gnashing of teeth.”
“Did you understand?” Jesus asked.
