Charles Spurgeon Commentary 1 John 3:9

"Whosoever is begotten of God doeth no sin, because his seed abideth in him: and he cannot sin, because he is begotten of God." — 1 John 3:9 (ASV)

Whoever is born of God does not commit sin;

That is to say, he does not live in it; it is not the tenor of his life.

He is not, outwardly, such that others could convict him of it, or inwardly, such that his own conscience could chide him with it—a man who loves sin.

For his seed remaineth in him: and he cannot sin because he is born of God.

Immortal principles forbid the child of God to sin; the new-born life within us keeps us holy. We have our imperfections and infirmities over which we mourn; but no child of God can live in sin, and love it. He hates it; he is like a sheep that may fall into the mire, but he will not wallow in it, as the swine do. As soon as possible, he is up again out of the mud and the filth. He goes sorrowing, with broken bones, when he perceives that he has grieved his God. His life as a whole is a holy life.
