1 John 3:6

“Whosoever abideth in him, &c.] As the branch in the vine, deriving all light, life, grace, holiness, wisdom, strength, joy, peace, and comfort from Christ; or dwells in him by faith, enjoys communion with him as a fruit of union to him; and stands fast in him, being rooted and grounded in him, and abides by him, his truths and ordinances, takes up his rest, and places his security in him, and perseveres through him: sinneth not; not that he has no sin in him, or lives without sin, but he does not live in sin, nor give up himself to a vicious course of life; for this would be inconsistent with his dwelling in Christ, and enjoying communion with him: whosoever sinneth; which is not to be…”

“He reasons from Christ's own entire separation from sin, that those in him must also be separate from it. abideth in him--as the branch in the vine, by vital union living by His life. sinneth not--In so far as he abides in Christ, so far is he free from all sin. The ideal of the Christian. The life of sin and the life of God mutually exclude one another, just as darkness and light. In matter of fact, believers do fall into sins (Jo1 1:8-10; Jo1 2:1-2); but all such sins are alien from the life of God, and need Christ's cleansing blood, without application to which the life of God could not be maintained. He sinneth not so long as he abideth in Christ. whosoever sinneth hath not seen…”

“Whosoever abideth in him - See 1 John 2:6. The word here employed (μένων menōn) properly means to remain, to continue, to abide. It is used of persons remaining or dwelling in a place, in the sense of abiding there permanently, or lodging there, and this is the common meaning of the word, Matthew 10:11; Matthew 26:38; Mark 6:10; Luke 1:56, “et saepe.” In the writings of John, however, it is quite a favorite word to denote the relation which one sustains to another, in the sense of being united to him, or remaining with him in affection and love; being with him in heart and mind and will, as one makes his home in a dwelling. The sense seems to be that we have some sort of relation to him…”

“Whosoever abideth in communion with him, by loving faith, sinneth not - While he so abideth. Whosoever sinneth certainly seeth him not - The loving eye of his soul is not then fixed upon God; neither doth he then experimentally know him - Whatever he did in time past. 1 John 3:7”

“3:6 continues to live in him (Greek menō): This indicates “abiding” and “remaining” (John 15:1-8) in contrast to departing into falsehood. To the extent that we live in continual, dependent fellowship with Christ and in faithfulness to the apostles’ teachings, we will not sin. • keeps on sinning: This verb denotes sin as an ongoing, repeated action. John was not saying that anyone who sins once does not know God (i.e., has no relationship with God). But if we persist in sin, we demonstrate a lack of relationship with God.”

“abideth: Jo1 2:28; Joh 15:4-7 whosoever: Jo1 3:2, Jo1 3:9, Jo1 2:4, Jo1 4:8, Jo1 5:18; Co2 3:18, Co2 4:6; Jo3 1:11 1 John 3:7”
