Question: 1 John 5:16, 1716If any man see his brother sin a sin which is not unto death, he shall ask, and he shall give him life for them that sin not unto death. There is a sin unto death: I do not say that he shall pray for it. 17All unrighteousness is sin: and there is a sin not unto death. (1 John 5:16‑17). Does this refer to blasphemy against the Holy Spirit, as in Matt. 12:31, 3231Wherefore I say unto you, All manner of sin and blasphemy shall be forgiven unto men: but the blasphemy against the Holy Ghost shall not be forgiven unto men. 32And whosoever speaketh a word against the Son of man, it shall be forgiven him: but whosoever speaketh against the Holy Ghost, it shall not be forgiven him, neither in this world, neither in the world to come. (Matthew 12:31‑32), Mark 3:2929But he that shall blaspheme against the Holy Ghost hath never forgiveness, but is in danger of eternal damnation: (Mark 3:29), Luke 12:1010And whosoever shall speak a word against the Son of man, it shall be forgiven him: but unto him that blasphemeth against the Holy Ghost it shall not be forgiven. (Luke 12:10)? or does the apostle speak of sin incurring the chastening of death without going farther? Q.
Answer: Here is what he lays down— “If any one see his brother sinning a sin not unto death, he shall ask, and He shall give him life for those that sin not unto death. There is a sin unto death: not about that do I say that he should make request. Every unrighteousness is sin; and there is a sin not unto death.”
The apostle had just spoken of the boldness or confidence to which grace entitles the children of God who walk in obedience and dependence on Him, as having life eternal in His Son. It is so real and great that, if we ask anything according to His will, He hears us; and if we know that He hears us whatsoever we ask, we know that we have the petitions which we have asked of Him. Nor is it only in what concerns ourselves. His love would have us divinely interested in our brethren as His children, and cherishing like confidence in Him touching them. But there is a caution. He carries on a holy discipline; and where a lack in self-judgment is, He may not only send sickness but death as a chastening. We read in 1 Cor. 11:29-3229For he that eateth and drinketh unworthily, eateth and drinketh damnation to himself, not discerning the Lord's body. 30For this cause many are weak and sickly among you, and many sleep. 31For if we would judge ourselves, we should not be judged. 32But when we are judged, we are chastened of the Lord, that we should not be condemned with the world. (1 Corinthians 11:29‑32) the plain fact, and the principle. Many at Corinth were falling asleep, because they did not judge their deplorable ways. This was a sin unto death in ever so many cases. Where the Lord is thus dealing, it would be lack of communion with Him to pray that such souls should live. When so judged, says the apostle Paul, we are chastened, or disciplined, by the Lord, that we may not be condemned with the world (which of course would be everlasting perdition). It is therefore as far as can be from the unforgivable sin of blasphemy against the Holy Spirit. It is the Lord’s dealing with a soul guilty of what He cannot allow to go on, and therefore calls him away, but with mercy assured, although there be withal chastening righteousness. It is a sin unto death; and we bow to God, instead of interceding. It does not seem some peculiarly heinous sin which brings destruction from God, but a sin of such special dishonor in its circumstances that He thus visits it. Such seems to have been the lying of Ananias and Sapphira in a day of great grace.
