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 children of God; and such we are. For this cause the world knoweth us not, because it knew him not. Beloved, now are we children of God, and it is not yet made manifest what we shall be. We know that, if he shall be manifested, we shall be like him; for we shall see him even as he is. And every one that hath this hope set on him purifieth himself, even as he is pure.

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

Whosoever is begotten of God doeth no sin, because his seed abideth in him: and he cannot sin, because he is begotten of God.

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

Hereby know we love, 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 with the tongue; but in deed and truth.
