1 John 3:1-3, 5, 9, 11, 16, 18

Behold, what manner of love the Father hath bestowed upon us, that we should be called the sons of God: therefore the world knoweth us not, because it knew him not. Beloved, now are we the sons of God, and it doth not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is. And every man that hath this hope in him purifieth himself, even as he is pure.

And ye know that he was manifested to take away our sins; and in him is no sin.

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.

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

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.

My little children, let us not love in word, neither in tongue; but in deed and in truth.
