In the last days, there will be a final harvest to separate wheat from barnyard grass. Do saints need to attend?

In the last days, there will be a final harvest, and the saints will participate in the harvest of wheat and barnyard grass respectively.

The metaphor of wheat and barnyard grass comes from Matthew 13: 24-30. Wheat barnyard grass and wheat barnyard grass are very similar, and we can't distinguish them for sure until the ear and heading bear fruit.
