@CharismaticLady made the distinction between sin that leads to death as it being sin that breaks the 10 commandments and sin that does not break the 10 Commandments, but that trespasses against God.
She alludes to the Lords prayer where we are taught to pray "Forgive us our trespasses as we forgive those who trespass against us." Forgiveness of our trespass is thus dependent on our forgiving others their trespass against us.
Further, she states that we are able not to sin:
18 We know that everyone who has been born of God does not keep on sinning, but he who was born of God protects him, and the evil one does not touch him.
Looking at the passages in context:
16 If anyone sees his brother committing a sin not leading to death, he shall ask, and God will give him life—to those who commit sins that do not lead to death. There is sin that leads to death; I do not say that one should pray for that. 17 All wrongdoing is sin, but there is sin that does not lead to death.
18 We know that everyone who has been born of God does not keep on sinning, but he who was born of God protects him, and the evil one does not touch him.
If anyone sees his brother (Brother in Christ?) committing a sin not leading to death, he shall ask (on behalf of this brother) and God will give him life- those brothers who commit sins that do not lead to death..
A couple of observations:
I do not think "brother" here refers to those already saved, or brothers in Christ, as the prayer will lead to God giving that "brother" life.
God having to give someone life, denotes that "Life" was not given before. (John equates Life, with Jesus- 2 the life was made manifest, and we have seen it, and testify to it and proclaim to you the eternal life, which was with the Father and was made manifest to us—)
If someone want's to argue loss of salvation and restoration to salvation, then they would have to negate:
"It is impossible.... 6 and then have fallen away, to restore them again to repentance, since they are crucifying once again the Son of God to their own harm and holding him up to contempt.
There is sin that leads to death; and John says one should not pray for that.
What is the unforgivable sin? Does it lead to death, or do you remain dead in your sin... Can the sin that leads to death be anything but the unforgivable sin and can those who are born again believers commit the unforgivable sin, or is the unforgivable sin rejection of the Holy Spirit by denying Him.
Not all sin prevents you from being reconciled to God, and pray for those who commit these sins, and God will restore them. There is a sin that prevents one from being reconciled to God.
Those that are reconciled to God, do not keep on sinning, because Christ protects them and the evil one does not touch the reconciled child of God.
Therefore, looking at the context, I do not agree with
@CharismaticLady that breaking the "Royal Law" as a born again believer is the sin that leads to death.
Only blasphemy of the Holy Spirit leads to death, and the passage in 1 John should be read with a hemaneutic, taking all of scripture in mind.
All born again believers do trespass and need to repent, and forgive and we should strive to live our lives without sinning. Living in the Spirit at all times, thereby not satisfying the lusts of the flesh. This is not an impossibility, as scripture is clear that we are no longer slaves to sin, so we can overcome every sin and we should endeavor to live in that victory.
18 We know that everyone who has been born of God does not keep on sinning,
but he who was born of God protects him, and the evil one does not touch him.
The righteousness of Christ covers all sin for those who have been made righteous by faith in the Lordship of Jesus Christ, and by confessing that He was raised from the dead.
