How do we know that God's judgment will separate the righteous from the wicked?

The certainty of God's judgment, as illustrated in the parable of the wheat and the tares, is affirmed in Scripture. Matthew 13:40-43 explicitly states that just as the tares are gathered and burned, so it shall be at the end of the harvest; the Son of Man will send forth His angels to gather all things that offend and separate them from the righteous. This separation underscores God's sovereignty and holiness, ensuring that His justice prevails. Moreover, the promise that the righteous will shine forth like the sun in the kingdom of their Father provides believers with hope, knowing that their faith in Christ will lead to eternal life, while the wicked face eternal punishment.
