Charles Spurgeon Commentary 1 John 3:6

"Whosoever abideth in him sinneth not: whosoever sinneth hath not seen him, neither knoweth him." — 1 John 3:6 (ASV)

Whosoever abideth in him sinneth not: whosoever sinneth hath not seen him, neither known him.

The man who dwells in Christ is the holy man; but the man who lives in sin is no child of God, for he proves by his evil conduct that he has no vital union with Christ. The fruit of Christianity is holiness; and if your life is a sinful one, if that is the main run and tenor of your life, you are none of His.

Whoever abideth in him sinneth not: whosoever sinneth hath not seen him, neither known him.

If this declaration related to any one act of sin, none of us could ever say that we have seen or known him, but it relates to the habit of sin — if we love sin, and live in sin, if the main course of our life is sinful, then we have not seen him, neither known him.
