2 Peter 1:2

Grace to you and peace be multiplied in the knowledge of God and of Jesus our Lord;

Grace to you and peace ... These words are similar, in fact, identical with the greeting used by Paul, upon which frequent comments have been made throughout this series.

In the knowledge of God ... This is that special kind of knowledge noted in the chapter heading. Concerning it, Moorehead said:

This is the knowledge that rests on fact, that comes to the believer as something supernatural, as being communicated by the Spirit of God, and therefore is true and complete.[10]

Peter's introduction of the subject of this accurate and complete knowledge here at the very outset "anticipates the attack that is coming upon the godless speculations of the false teachers in chapter 2."[11] Some scholars once thought that Peter's attack against the false knowledge of the Gnostics required a hate dating of the letter; but it is now known that the types of gnosticism refuted by Peter were prevalent in apostolic times, and that there is no reason whatever for dating the epistle outside the lifetime of its author.
