1 John 5:18

“We know that whosoever is born of God, &c.] Who is regenerated by his Spirit and grace, and quickened by his power; who has Christ formed in him, and is made a partaker of the divine nature, and has every grace implanted in him: sinneth not; the sin unto death; nor does he live in sin, or is under the power and dominion of it, though he does not live without it; (see Gill on “<620309>1 John 3:9”); but he that is begotten of God; the Vulgate Latin version reads, “the generation of God keeps or preserves him”; that is, that which is born in him, the new man, the principle of grace, or seed of God in him, keeps him from notorious crimes, particularly from sinning the sin unto death, and from…”

“(Jo1 3:9.) We know--Thrice repeated emphatically, to enforce the three truths which the words preface, as matters of the brethren's joint experimental knowledge. This Jo1 5:18 warns against abusing Jo1 5:16-17, as warranting carnal security. whosoever--Greek, "every one who." Not only advanced believers, but every one who is born again, "sinneth not." he that is begotten--Greek aorist, "has been (once for all in past time) begotten of God"; in the beginning of the verse it is perfect.

Though he may fall into sin, and grieve his brethren, yet we are never to cease to pray for a true Christian: we are never to feel that he has committed the sin which has never forgiveness, and that he has thrown himself beyond the reach of our prayers. This passage, in its connection, is a full proof that a true Christian “will” never commit the unpardonable sin, and, therefore, is a proof that he will never fall from grace. Compare the notes at Hebrews 6:4-8; Hebrews 10:26. On the meaning of…”

“Yet this gives us no encouragement to sin: on the contrary, it is an indisputable truth, he that is born of God - That sees and loves God. Sinneth not - So long as that loving faith abides in him, he neither speaks nor does anything which God hath forbidden. He keepeth himself - Watching unto prayer. And, while he does this, the wicked one toucheth him not - So as to hurt him. 1 John 5:19”
