saved still have sin
Where are you reading from? On my book it says otherwise:
1 John 2:4 He that saith, I know him, and keepeth not his commandments, is a liar, and the truth is not in him.
6 He that saith he abideth in him ought himself also so to walk, even as he walked.
1 John 3:6 Whosoever abideth in him sinneth not: whosoever sinneth hath not seen him, neither known him.
9 Whosoever is born of God doth not commit sin; for his seed remaineth in him: and he cannot sin, because he is born of God.
