The message in the parable of the weeds is to teach Christians to be aware of false teaching. In the parable, Jesus tells of a farmer who sowed good seed in his field, but an enemy came and sowed weeds among the wheat. The farmer decided to let the wheat and the weeds grow together until harvest time. The message of the parable is that in the world, there will always be false teachings and evil, but Christians should be discerning and not be deceived by false teachings. They should continue to grow and bear fruit, knowing that at the end of the age, the Lord will separate the wheat from the weeds.
