He who sins is of the devil, for the devil has been sinning from the beginning. To this end the Son of God was revealed, that he might destroy the works of the devil.

 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.
