2 Peter 1:2

‘Grace to you and peace be multiplied in the knowledge of God and of Jesus our Lord,'

The combined greetings of ‘grace' (a Greek greeting) and ‘peace' (a Jewish greeting) again reflect the unity of God's people. But to the Christian ‘grace' reflects more than just ‘well-being', it reflects the unmerited, active love and compassion of God at work on his behalf. Peace also reflects their wellbeing in Him, and also has in mind the peace and contentment of a settled heart, the ‘peace which passes all understanding' (Philippians 4:7). So to some extent they are interchangeable. The main idea in Peter's mind is their spiritual wellbeing brought about through the activity of a gracious and compassionate God.

‘Be multiplied.' Compare 1 Peter 1:2; Jude 1:2. Wellbeing is to be multiplied towards them within the sphere of the spiritual knowledge (epignosis) of ‘God' and of ‘Jesus our Lord'. Or ‘of our God, even Jesus our Lord'. In Jesus' own words, ‘no one knows the Father but the Son, and he to whom the Son pleases to reveal Him' (Matthew 11:27).
