We just learned about one of Jesus' teaching stories called the Parable of the Sower
Another parable Jesus told was called the Parable of the Weeds.
He said that God's kingdom is like a field where the farmer planted wheat seeds, but when he was sleeping a bad person came and planted weeds right next to his wheat seeds.
The farmer's helpers asked if they should pull the weeds out, but the farmer said they couldn't because that would uproot the wheat too.
He said to wait until the wheat is grown. Then go pull the weeds out to be burned up and bring the wheat to the barn.
Jesus was really talking about people, and saying that the bad people of the world would not go to Heaven, they would be thrown out like the weeds. But the good people of the earth would be brought to Heaven to live with him forever.
