John Trapp on 2 Peter 1:4

Verſe 4. Exceeding great and precious] Every precious ſtone hath an egregious vertue in it:Cardan. Subti. l 7. ſo hath every promiſe. The promiſes, ſaith one, are a precious book, every leaf drops mirthe and mercy. The weak Chriſtian cannot open, read, apply it; Chriſt can, and will for him.

That by theſe ye might be partakers] As the Sunne when it applies it's beams to a fitly diſpoſed matter, and ſtaies upon it, begins to beget life and motion, and makes a living creature; ſo do the promiſes applied to the heart make a new creature, See a Cor. 3 6.

Of the divine nature] That is, of thoſe divine qualities, called elſewhere, The image of God, The life of God, &c. whereby we reſemble God, not only as a picture doth a man in outward lineaments, but as the childe doth his father in countenance and conditions. It was no abſurd ſpeech of him that ſaid, That the high parts that are ſeen in heroicall perſons do plainly ſhew, that there is a God. Neither can I here but inſert the ſaying of another, Well may grace be called the divine nature: for as God brings light out of darkneſſe, comfort out of ſorrow, riches out of poverty, and glory out of ſhame; ſo doth grace turn the dirt of diſgrace into gold, &c. As Moſes his hand, it turns a ſerpent into a rod.
