'Remaining' in the Bible

every one who is remaining in him doth not sin; every one who is sinning, hath not seen him, nor known him.

Every one who is hating his brother -- a man-killer he is, and ye have known that no man-killer hath life age-during in him remaining,

and we -- we have known and believed the love, that God hath in us; God is love, and he who is remaining in the love, in God he doth remain, and God in him.
