17 all unrighteousness is sin, and there is sin not unto death.

1 John 5:17 Meaning and Commentary

1 John 5:17

All unrighteousness is sin
All unrighteousness against God or man is a sin against the law of God, and the wrath of God is revealed against it, and it is deserving of death; yet all unrighteousness is not unto death, as the sins of David, which were unrighteousness both to God and man, and yet they were put away, and he died not; Peter sinned very foully, and did great injustice to his dear Lord, and yet his sin was not unto death; he had repentance unto life given him, and a fresh application of pardoning grace:

and there is a sin not unto death;
this is added for the relief of weak believers, who hearing of a sin unto death, not to be prayed for, might fear that theirs were of that kind, whereas none of them are; for though they are guilty of many unrighteousnesses, yet God is merciful to them and forgives, ( Hebrews 8:12 ) , and so they are not unto death.

16 If any one may see his brother sinning a sin not unto death, he shall ask, and He shall give to him life to those sinning not unto death; there is sin to death, not concerning it do I speak that he may beseech;
17 all unrighteousness is sin, and there is sin not unto death.
18 We have known that every one who hath been begotten of God doth not sin, but he who was begotten of God doth keep himself, and the evil one doth not touch him;
19 we have known that of God we are, and the whole world in the evil doth lie;
