Luke 16:31

εἶπε δὲ : Abraham does not plead impossibility as in reference to the first request; he simply declares his unbelief in the utility of the plan for converting the five. The denizens of Paradise set little value on the unusual as a means of grace. Abraham does not say that a short-lived sensation could not be produced; he does say that they would not be persuaded (πεισθήσονται), i.e., to repent (Hahn). By taking πεισθήσονται as meaning something less than μετανοήσουσιν, and emphasising the difference between ἐκ νεκρῶν ἀναστῇ and ἀπὸ νεκρῶν πορευθῇ (Luke 16:30), Trench (Notes on the Parables) makes this point: “A far mightier miracle than you demand would be ineffectual for producing a far slighter effect”. It is doubtful if the contrast be legitimate in either case; certainly not as between “repent” and “be persuaded”. In the other case there may be the difference between an apparition and a resurrected man. It may be noted that the resurrection of Christ and of Christians is spoken of as ἐκ νεκρῶν (vide Luke 20:35), while the general resurrection is ἡ ἀνάσ. τῶν νεκρῶν (e.g., 1 Corinthians 15:42).
