Final days of judgment: As the parable begins, the idea of Adam, Eve, the garden of Eden & the serpent come to mind. When God made the garden along with Adam & Eve, everything was good. He sowed good seed into a good field. Then along comes the serpent, who plants the idea of disobedience into Eve's mind. She disobeys God, eats from the Tree of Good/Evil, and sin entered into the world. God had the chance to destroy everything, He did not. Instead He cast them out of the garden. Later on we all wait for the final day of judgement or the "final harvest." Where God will separate the good from the bad (wheat from the weeds). The good (wheat) He will take in & the bad (weeds) will be cast into the fire (Hell). Just as one does during a harvest.
