Grace, mercy and peace from God the Father and from Jesus Christ, the Father’s Son, will be with us in truth and love. 2 John 1:3
The Jamieson, Fausset and Brown Commentary explain this verse in this way:
grace ... mercy ... peace—"Grace" covers the sins of men; "mercy," their miseries. Grace must first do away with man's guilt before his misery can be relieved by mercy. Therefore grace stands before mercy. Peace is the result of both, and therefore stands third in order. Casting all our care on the Lord, with thanksgiving, maintains this peace. 2 John 1:3
Grace, mercy and peace can only be found in the truth and love of the Father's Son, Jesus! The author goes on to say that there are imposters out there preaching a false doctrine and we, the church, need to be wary of them. We need to compare the message we hear with the Word and walk in Love: "And this is love: that we walk in obedience to his commands. As you have heard from the beginning, his command is that you walk in love." 2 John 1:6
