This article offers a new reading of what it means in 2 Pet 1,4 to participate in the «divine nature». The divine fu/sij («nature») in 2 Pet 1,4 refers not to an abstract, divine «essence» or «being», but to God’s dynamic «character expressed in action» in accordance with his promises. Being a fellow participant (koinwno/j) of this «nature» thus refers to taking part in the eschatological realization of the «new heavens and a new earth in which righteousness dwells» (cf. ta\ e)pagge/lmata in 2 Pet 1,4 with e)pagge/lma in 2 Pet 3,13).
