Whoever remains in him doesn't sin. Whoever sins hasn't seen him, neither knows him.
hath not seen him, neither known him; that is, he has never seen Christ with an eye of faith; he has never truly and spiritually seen the glory, beauty, fulness, and suitableness of Christ, his need, and the worth of him; he has never seen him so as to enjoy him, and have communion with him; for what communion hath Christ with Belial, or light with darkness, or righteousness with unrighteousness? 2 Corinthians 6:14, nor has he ever savingly known him, or been experimentally acquainted with him; for though he may profess to know him in words, he denies him in works.
