This is evidence of the righteous judgment of God and is intended to make you worthy of the kingdom of God, for which you are also suffering.
For it is indeed just of God to repay with affliction those who afflict you
—2 Thessalonians 1:5–6

Our steadfastness in suffering is God’s judgment flooding the present. It is the realization of the future judgment in the now. Also, for believers, they partake in judgment too, it’s just their vindication.
