Hebrews 6:10

God had taken note of the readers’ commendable Christian conduct and would justly reward them for it. Therefore they should persevere in it and not turn aside from it (i.e., apostatize). "Not unjust" is understatement; God is eminently just. This is also litotes, a figure of speech that sets forth a positive idea by stating its negative opposite (cf. Acts 12:18; Acts 15:2; Acts 17:4; Acts 17:12; Acts 19:24; Acts 27:20; et al.). [Note: For further discussion of rhetorical elements in Hebrews, see Trotter, pp. 164-77.]
