8.] For by grace (the article shews us the import of the sentence—to take up and expand the parenthetic clause χάριτί ἐστε σεσωσμένοι above: but not barely so: that clause itself was inserted on account of the matter in hand being a notable example of the fact, and this γάρ takes up also that matter in hand—the ὑπερβάλλον πλοῦτος κ.τ.λ) ye are (perf.) saved, through [your] (or [the], but the possessive article is preferable, see below: ‘the’ would make both objective. The abstract, ‘through faith,’ must be the rendering if the article be omitted) faith (the dative above expressed the objective instrumental condition of your salvation,—this διὰ the subjective medial condition: it has been effected by grace and apprehended by faith): and this (not your faith, as Chrys. οὐδὲ ἡ πίστις, φησίν, ἐξ ὑμῶν: so Thdrt., al., Corn.-a-Iap., Beza, Est., Grot., Beng., all.;—this is precluded (not by the gender of τοῦτο, but) by the manifestly parallel clauses οὐκ ἐξ ὑμῶν and οὐκ ἐξ ἔργων, of which the latter would be irrelevant as asserted of πίστις, and the reference of ver. 9 must therefore be changed:—but, as Calv., Calov., Rück., Harl., Olsh., Mey., De W., Stier, al., ‘your salvation;’ τὸ σεσωσμένοι εἶναι, as Ellic.) not of yourselves, GOD’S (emphatic) is the gift (not, as E. V. ‘it is the gift of God’ (θεοῦ δῶρον),—τὸ δῶρον, viz. of your salvation: so that the expression is pregnant—q. d., ‘but it is a gift, and that gift is God’s.’ There is no occasion, as Lachm., Harl., and De W., to parenthesize these words: they form a contrast to οὐκ ἐξ ὑμ., and a quasi-parallel clause to ἵνα μή τις καυχήσ. below): not of works (for ἐξ ἔργων, see on Rom. 3:4, and Gal. 2:16), that no man should boast (on the proposition implied, see on Rom. 4:2. ἵνα, has in matter of fact its strictest telic sense. With God, results are all purposed; it need not be understood, when we predicate of Him a purpose in this manner, that it was His main or leading aim;—but it was one of those things included in His scheme, which ranked among His purposes).
