1. Johannes 5:16

If any . . . see--on any particular occasion; Greek aorist. his brother--a fellow Christian. sin a sin--in the act of sinning, and continuing in the sin: present. not unto death--provided that it is not unto death. he shall give--The asker shall be the means, by his intercessory prayer, of God giving life to the sinning brother. Kindly reproof ought to accompany his intercessions. Life was in process of being forfeited by the sinning brother when the believer's intercession obtained its restoration. for them--resuming the proviso put forth in the beginning of the verse. "Provided that the sin is not unto death." "Shall give life," I say, to, that is, obtain life "for (in the case of) them that sin not unto death." I do not say that he shall pray for it--The Greek for "pray" means a REQUEST as of one on an equality, or at least on terms of familiarity, with him from whom the favor is sought. "The Christian intercessor for his brethren, John declares, shall not assume the authority which would be implied in making request for a sinner who has sinned the sin unto death (Sa1 15:35; Sa1 16:1; Mar 3:29), that it might be forgiven him" [TRENCH, Greek Synonyms of the New Testament]. Compare Deu 3:26. Greek "ask" implies the humble petition of an inferior; so that our Lord never uses it, but always uses (Greek) "request." Martha, from ignorance, once uses "ask" in His case (Joh 11:22). "Asking" for a brother sinning not unto death, is a humble petition in consonance with God's will. To "request" for a sin unto death [intercede, as it were, authoritatively for it, as though we were more merciful than God] would savor of presumption; prescribing to God in a matter which lies out of the bounds of our brotherly yearning (because one sinning unto death would thereby be demonstrated n…

In this chapter the apostle asserts, I. The dignity of believers (Jo1 5:1). II. Their obligation to love, and the trial of it (Jo1 5:1-3). III. Their victory (Jo1 5:4, Jo1 5:5). IV. The credibility and confirmation of their faith (Jo1 5:6-10). V. The advantage of their faith in eternal life (Jo1 5:11-13). VI. The audience of their prayers, unless for those who have sinned unto death (Jo1 5:14-17). VII. The preservation from sin and Satan (Jo1 5:18). VIII. Their happy distinction from the world (Jo1 5:19). IX. Their true knowledge of God (Jo1 5:20), upon which they must depart from idols (Jo1 5:21).

5:16 Sins that lead to death are those involving apostasy (see Matt 12:31-32; Heb 6:4-6). In the context of this letter, apostasy involves leaving the apostolic faith and joining a heretical, anti-Christian movement such as those denounced in John’s letters.
