This is evidence of the righteous judgment of God, that you may be considered worthy of the kingdom of God, for which you are also suffering—
5 A demonstration of the righteous judgment of God. Without mentioning the exposition given by others, I am of opinion that the true meaning is this — that the injuries and persecutions which innocent and pious persons endure from the wicked and abandoned, shew clearly, as in a mirror, that God will one day be the judge of the world.
Having mentioned their persecutions and tribulations, which they endured principally for the cause of Christ, the apostle proceeds to offer several things for their comfort under them; as, I. He tells them of the present happiness and advantage of their sufferings, Th2 1:5. Their faith being thus tried, and patience exercised, they were improved by their sufferings, insomuch that they were counted worthy of the kingdom of God.
