James 5:19
17 Elijah was a human being like us, and he prayed earnestly that it would not rain and there was no rain on the land for three years and six months! 18 Then he prayed again, and the sky gave rain and the land sprouted with a harvest. 19 My brothers and sisters, if anyone among you wanders from the truth and someone turns him back, 20 he should know that the one who turns a sinner back from his wandering path will save that person’s soul from death and will cover a multitude of sins.
Jude 1:23
21 maintain yourselves in the love of God while anticipating the mercy of our Lord Jesus Christ that brings eternal life. 22 And have mercy on those who waver; 23 save others by snatching them out of the fire; have mercy on others, coupled with a fear of God, hating even the clothes stained by the flesh. 24 Now to the one who is able to keep you from falling, and to cause you to stand, rejoicing, without blemish before his glorious presence, 25 to the only God our Savior through Jesus Christ our Lord, be glory, majesty, power, and authority, before all time, and now, and for all eternity. Amen.
Notes and References
"... William Brosend is right to note the parallel to the way James ends, where the discussion is also about restoring a wandering sinner, saving them from eternal death and thereby covering a multitude of sins (James 5:19-20). This may suggest that Jude knew James's sermon or at least knew James's teaching on such a matter and agreed with it. The same message can be conveyed in two different wavs: James's approach is sapiential, he stands in the tradition of the sage: Jude's approach is apocalyptic and prophetic, he stands in the tradition of prophets who speak on matters eschatological. Yet both want to deal with the erring in a compassionate and merciful way when it comes to pastoral practice ..."
