1 John 3:1 in the King James Version
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.
Context
1 See how great a love the Father has given to us, that we should be called children of God! For this cause the world doesn’t know us, because it didn’t know him.
2 Beloved, now we are children of God. It is not yet revealed what we will be; but we know that when he is revealed, we will be like him, for we will see him just as he is.
