You know that he was revealed to take away our sins, and in him is no sin.

 3:1-2 See what kind of love the Father has given to us, that we should be called the children of God--and such we indeed are. The reason why the world does not recognize us is that it did not recognize him. Beloved, even as things are we are children of God, and it has not yet been made clear what we shall be. We know that, if it shall be made clear, we shall be like him because we shall see him as he is.
