The parable of the wheat and the tares illustrates that

The parable of the wheat and the tares is a story told by Jesus in the Bible to illustrate the coexistence of good and evil in the world. In the story, a man sowed wheat in his field, but an enemy came and sowed tares (weeds) among the wheat. When the wheat sprouted and began to grow, the tares also grew up with them. The man's servants asked him if they should pull out the tares, but he told them to let them grow together until the harvest, when they would be separated and the wheat would be gathered into the barns while the tares would be burned. This parable teaches that both good and evil exist in the world, and it is not always possible to distinguish them or separate them completely. It is also a warning against judging or trying to eliminate perceived "enemies" prematurely, as this can cause harm to the innocent as well. Ultimately, the parable illustrates the idea that the final judgment and separation of good and evil will occur at the end of time, when God will separate the righteous from the wicked.
