Passage
Grace shall be with you, mercy, peace from God [the] Father, and from [the] Lord Jesus Christ, the Son of the Father, in truth and love.
Grace shall be with you, mercy, peace from God [the] Father, and from [the] Lord Jesus Christ, the Son of the Father, in truth and love.
2 John 1:1 The elder to [the] elect lady and her children, whom *I* love in truth, and not *I* only but also all who have known the truth,
2 John 1:2 for the truth's sake which abides in us and shall be with us to eternity.
2 John 1:3 Grace shall be with you, mercy, peace from God [the] Father, and from [the] Lord Jesus Christ, the Son of the Father, in truth and love.
2 John 1:4 I rejoiced greatly that I have found of thy children walking in truth, as we have received commandment from the Father.
2 John 1:5 And now I beseech thee, lady, not as writing to thee a new commandment, but that which we have had from [the] beginning, that we should love one another.
The verse centers on "grace", "mercy", "shall", "peace", "father", "lord", "jesus", and "christ". It is saying that the verse draws attention to "grace" and "mercy", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 2's "for the truth's sake which abides in..." into verse 4's "I rejoiced greatly that I have found...", so "grace" and "mercy" belong inside that flow. In 2 John context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "grace" and "mercy" with trust shaped by these words, not by a vague optimism outside the passage.
