James 5:19

ἀδελφοί μου introduces another and a last topic closely connected with prayer, namely Conversion.

τῆς�. The clause ἐάν τις ἐν ὑμῖν makes it clear that the truth spoken of is the Christian truth, the saving truth of the gospel, almost equivalent to ἡ πίστις. Comp. 1 Timothy 6:10 ῥίζα γὰρ πάντων τῶν κακῶν ἐστὶν ἡ φιλαργυρία, ἧς τινες ὀρεγόμενοι�, 21 ἀντιθέσεις τῆς ψευδωνύμου γνώσεως, ἥν τινες ἐπαγγελλόμενοι περὶ τὴν πίστιν ἠστόχησαν, 2 Timothy 2:18 οἵτινες περὶ τὴν�, λέγοντες�, καὶ�. Therefore the conversion spoken of here is not conversion from heathenism or Judaism, but from some perversion of the Christian truth or morality such as is indicated in the passages cited.
