In the economy of life which he inaugurates and inspires.
Availeth (ἰσχύει)
Has any significance or practical power. The verb in Paul only here and Phi 4:13. See on 2Th 1:9.
Which worketh (ἐνεργουμένη)
See on 1Th 2:13. Middle voice, comp. Rom 7:5; 2Co 1:6; 2Co 4:12; 2Th 2:7; Eph 3:20. Not passive, as by many Roman Catholic expositors, faith which is wrought by love.
By love (δἰ ἀγάπης)
Not that justification is through love; but the faith of the justified, which is their subjective principle of life, exhibits its living energy through love in which the whole law is fulfilled (Gal 5:14). See 1Ti 1:5; 1Th 1:3; 1Co 13:1-13.
