Purpose according to election (ἡ κατ' ἐκλογὴν πρόθεσις)
For πρόθεσις purpose, see on the kindred verb προέθετο, Rom 3:25, and compare Rom 8:28. The phrase signifies a purpose so formed that in it an election was made. The opposite of one founded upon right or merit. For similar phrases see Act 19:20; κατὰ κράτος according to might, mightily; Rom 7:13, καθ' ὑπερβολὴν according to excess, exceedingly. See note.
Might stand (μένῃ)
Lit., abide, continue: remain unchangeable. This unchangeableness of purpose was conveyed in His declaration to Rebecca. Contrast with come to nought (Rom 9:6).
Of works (ἐξ)
Lit., out of. By virtue of.
Calleth (καλοῦντος)
Eternal salvation is not contemplated. “The matter in question is the part they play regarded from the theocratic stand-point” (Godet).
