This is an obvious sign of the righteous judgment of God, to the end that you may be counted worthy of the Kingdom of God, for which you also suffer.
May be accounted worthy. There are no persecutions that are to be reckoned of such value as to make us worthy of the kingdom of God, nor does Paul dispute here as to the ground of worthiness, but simply takes the common doctrine of Scripture — that God destroys in us those things that are of the world, that he may restore in us a better life; and farther, that by means of afflictions he shews us the value of eternal life. In short, he simply points out the manner in which believers are prepared and, as it were, polished under God’s anvil, inasmuch as, by afflictions, they are taught to renounce the world and to aim at God’s heavenly kingdom. Farther, they are confirmed in the hope of eternal life while they fight for it. For this is the entrance of which Christ discoursed to his disciples. (Matthew 7:13; Luke 13:24)
