Paul, Silvanus and Timothy greet the church of the Thessalonians, in God our Father and the Lord Jesus Christ, with grace and peace. They then say they ought always to give thanks to God for them, as is right, because their faith is growing abundantly and the love of every one of them is increasing. For that reason the missionaries boast about them among the churches of God, for their steadfastness and faith in all the persecutions and afflictions they endure.
This is evidence of God's righteous judgment, that they may be considered worthy of the kingdom of God, for which they are also suffering. It is just for God to repay with affliction those who afflict them, and to give relief to them and to the missionaries when the Lord Jesus is revealed from heaven with his mighty angels in flaming fire, inflicting vengeance on those who do not know God and do not obey the gospel. They will suffer the punishment of eternal destruction, away from the presence of the Lord and from the glory of his might, when he comes on that day to be glorified in his saints and marveled at among all who have believed.
To this end Paul prays always for them, that God may make them worthy of his calling and fulfill every resolve for good and every work of faith by his power, so that the name of our Lord Jesus may be glorified in them, and they in him, according to the grace of our God and the Lord Jesus Christ.
