1 John 3:1-2; 1 John 3:10; 1 John 5:2
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 .
In this the children of God are manifest, and the children of the devil: whosoever doeth not righteousness is not of God, neither he that loveth not his brother.
By this we know that we love the children of God, when we love God, and keep his commandments.
