How do we know the separation of the righteous and the wicked will happen?

Christ's teaching in the parable of the wheat and weeds provides clear assurance that a day of separation will occur at the end of the world. According to Matthew 13:30, Christ will gather His own people, the wheat, into His barn, while the weeds, representing the unconverted, will be cast into a furnace of fire. This event is certain, as angels will be the reapers who distinguish between the righteous and the wicked with unerring judgment. The conclusion of this parable underlines the severity of neglecting God and the hope of eternal life for the faithful. Believers can find comfort in knowing that they will ultimately experience a perfected and glorious communion free from the corruption of the world.
