Passage
Grace to you, and peace from God our Father, and [the] Lord Jesus Christ.
Grace to you, and peace from God our Father, and [the] Lord Jesus Christ.
2 Thessalonians 1:1 Paul and Silvanus and Timotheus to the assembly of Thessalonians in God our Father and [the] Lord Jesus Christ.
2 Thessalonians 1:2 Grace to you, and peace from God our Father, and [the] Lord Jesus Christ.
2 Thessalonians 1:3 We ought to thank God always for you, brethren, even as it is meet, because your faith increases exceedingly, and the love of each one of you all towards one another abounds;
2 Thessalonians 1:4 so that we ourselves make our boast in you in the assemblies of God for your endurance and faith in all your persecutions and tribulations, which ye are sustaining;
The verse centers on "grace", "peace", "father", "lord", "jesus", and "christ". It is saying that salvation is received as God's gift through faith, so boasting is pushed out by the wording itself.
The nearby context moves from verse 1's "Paul and Silvanus and Timotheus to the..." into verse 3's "We ought to thank God always for...", so "grace" and "peace" belong inside that flow. In 2 Thessalonians context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "grace" and "peace" with trust shaped by these words, not by a vague optimism outside the passage.
