From Paul, Silvanus, and Timothy:
References for 2 Thessalonians 1:1
To the church of the Thessalonians, which is in God our Father, and in the Lord Jesus Christ.Grace and peace to all of you from God our Father and the Lord Jesus Christ.
Brothers and sisters, we must always thank God for you. This is only right because your faithfulness is growing by leaps and bounds, and the love that all of you have for each other is increasing.
References for 2 Thessalonians 1:3
That's why we ourselves are bragging about you in God's churches. We tell about your endurance and faithfulness in all the harassments and trouble that you have put up with.
This shows that God's judgment is right, and that you will be considered worthy of God's kingdom for which you are suffering.
After all, it's right for God to pay back the ones making trouble for you with trouble
and to pay back you who are having trouble with relief along with us. This payback will come when the Lord Jesus is revealed from heaven with his powerful angels.
He will give justice with blazing fire to those who don't recognize God and don't obey the good news of our Lord Jesus.
They will pay the penalty of eternal destruction away from the Lord's presence and away from his mighty glory.
This will happen when he comes on that day to receive honor from his holy people and to be admired by everyone who has believed—and our testimony to you was believed.
We are constantly praying for you for this: that our God will make you worthy of his calling and accomplish every good desire and faithful work by his power.
Then the name of our Lord Jesus will be honored by you, and you will be honored by him, consistent with the grace of our God and the Lord Jesus Christ.
