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 Corinthians 1:1 Paul, apostle of Jesus Christ by God's will, and the brother Timotheus, to the assembly of God which is in Corinth, with all the saints who are in the whole of Achaia.
2 Corinthians 1:2 Grace to you, and peace from God our Father, and [the] Lord Jesus Christ.
2 Corinthians 1:3 Blessed [be] the God and Father of our Lord Jesus Christ, the Father of compassions, and God of all encouragement;
2 Corinthians 1:4 who encourages us in all our tribulation, that we may be able to encourage those who are in any tribulation whatever, through the encouragement with which we ourselves are encouraged of God.
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 apostle of Jesus Christ by God's..." into verse 3's "Blessed be the God and Father of...", so "grace" and "peace" belong inside that flow. In 2 Corinthians 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.
