A.T. Robertson Commentary 2 Peter 1:6

"and in [your] knowledge self-control; and in [your] self-control patience; and in [your] patience godliness;" — 2 Peter 1:6 (ASV)

Temperance (την εγκρατειαν). Self-control. Old word (from εγκρατης, εν and κρατος, one holding himself in as in Tit 1:8), in N.T. only here, Acts 24:25; Galatians 5:23. The opposite of the πλεονεξια of the heretics.

Patience (την υπομονην). For which see Jas 1:3.

Godliness (την ευσεβειαν). For which see verse 3.
