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.

… 11 For this is the message that ye heard from the beginning, that we should love one another.

… 14 We know that we have passed from death unto life, because we love the brethren. He that loveth not his brother abideth in death.

… 16 Hereby perceive we the love of God, because he laid down his life for us: and we ought to lay down our lives for the brethren.
– 1Jn 3:9,11,14,16
