A spirit of fearfulness (pneuma deilias). Here pneuma is the charisma of 2Ti 1:6, the human spirit as endowed by the Holy Spirit (Rom 8:15). Deilia is an old word (deilos, deidō) and always in a bad sense of cowardice, only here in N.T.
Of power (dunameōs). One of Paul’s characteristic words (Rom 1:16).
Of love (agapēs). One of the gifts of the Spirit (Gal 5:22). “Which drives out fear” (Lock) as in 1Jo 4:18.
Of discipline (sōphronismou). Late Koiné[28928]š word (from sōphronizō, to control), self-control, here only in N.T. See note on 1Ti 2:9 for sōphrosunē.
