a manifest token of the righteous judgment of God, to the end that ye should be counted worthy of the kingdom of God, for the sake of which ye also suffer;
Enemies hunted and harassed the believers in Thessalonica, and outsiders took that as proof God had left them. Paul reads it the other way: their patient endurance is a visible sign of God's righteous judgment, and of the kingdom they suffer for.
A sign pointing forward, not backward
Their suffering pointed forward. It showed where they stood with God, and how He would deal with those who attacked them.
The persecutions the Thessalonians endured proved that they were "considered worthy of the kingdom of God." God's judgment would bring this into the open. It would also show what the persecutors had done.
Their pagan neighbours read the same suffering the opposite way.
God, whatever people might be, was righteous. Their pagan friends might point to their sufferings as proof that the gods were rightly angry — the gods whose altars they had left and whose worship they condemned. They might also taunt them that their God did nothing to help them. The apostle drew a very different conclusion, and he set it before them. Their sufferings proved that they were God's people. Rest would be their portion, along with Paul and God's other people then on earth, when God's judgment from heaven overtakes the godless in the world.
"Considered worthy" — not earned standing
Does endurance buy a place in the kingdom? The answer separates two very different things.
This worthiness, here and in Matthew, is not about standing before God. Forgiveness of sins and acceptance with God rest on grace alone, never on merit of any kind (Eph. 2:8). The point is not relationship but discipleship. And suffering for Christ's sake is a prime mark of a true follower of our Lord. To shirk the cross is to forfeit the title of a worthy witness in the world for the Lord Jesus. And in the same way, to show patient endurance under fiery trials for the name of Christ is to proclaim the unswerving loyalty which marks one worthy of the devotion he professes to his Master.
Not merit — grace acknowledged
If nothing is merited, why is the word "righteous" used at all? Because God is acknowledging what He Himself has worked.
He does not mean or say that suffering, any more than working, could give any title to acceptance from the Righteous God. Someone like Paul could never say such a thing. It was grace (as he says again to the Philippians) that gave them even to suffer for Christ's sake. But grace had righteous title to count them worthy. And to acknowledge what grace had produced in them was itself righteousness.
Why God permits the pressure
Bearing wrong patiently takes faith. And the pressure is doing something in them.
To bear wrongful suffering patiently takes faith in a righteous God. He will not always let evil go unchecked, but will judge at the proper time. God allows this persecution against His people now for their own good. It is a training that molds character. It produces in them a true submission to authority as subjects of the King, and so makes them "worthy of the kingdom of God." How thankful we ought to be for this wise way in which God secures for us the greatest good.
The kingdom they suffer for
The "kingdom of God" here is not a vague word for heaven. Writers connect it to Christ's coming reign on earth — the reign they suffer for.
"The kingdom" implies Christ's coming to reign over the earth. In 1 Thess. 2:12 the apostle speaks of God calling to this, as an encouragement to walking worthily of God; and 2 Thess. 1 shows that the enemy used their persecutions and troubles to claim the day of the Lord had already come. Even before he clears away this delusion, the apostle treats their troubles the other way round. They are a manifest token of the righteous judgment of God, "that you may be considered worthy of the kingdom of God, for which you are also suffering."
The coming reversal
The verse looks ahead to a reversal that has not yet happened, and that shapes what a Christian expects now.
Let us, dear fellow-Christians, clearly grasp that the kingdom of God must suffer. "Indeed, all who desire to live a godly life in Christ Jesus will be persecuted." Soon the tables will be turned. The troubled shall rest, and the troublers be punished. God's kingdom shall triumph; man's shall perish. In the near future our calling is glory. Our present calling is to suffer in true and hearty sympathy with His kingdom and its rejected heavenly King — and may our God count us worthy of it.
Summary
- Token — Their suffering was not a sign of God's displeasure. It was proof that they were His people, and that judgment will fall the other way.
- Grace — Worthiness here is never merit; forgiveness and acceptance are by grace alone. The issue is discipleship, not relationship.
- Righteous — Grace gave them their suffering. Grace also has righteous title to own what it produced in them.
- Training — God permits the pressure as a school, forming subjects fit for the King they will live under.
- Reversal — The kingdom they suffer for is Christ's coming reign. When He appears, the troubled will rest and their persecutors will face judgment.
