Adam Clarke on 2 Peter 1:6

Temperance - A proper and limited use of all earthly enjoyments, keeping every sense under proper restraints, and never permitting the animal part to subjugate the rational.

Patience - Bearing all trials and difficulties with an even mind, enduring in all, and persevering through all.

Godliness - Piety towards God; a deep, reverential, religious fear; not only worshipping God with every becoming outward act, but adoring, loving, and magnifying him in the heart: a disposition indispensably necessary to salvation, but exceedingly rare among professors.
