HIS PURPOSE=TO DESTROY THE WORKS OF THE DEVIL...!!!

"Whosoever committeth sin transgresseth also the law:for sin is the transgression of the law.
And ye know that he was manifested to take away our sins;and in him is no sin.
Whosoever abideth in him sinneth not:whosoever sinneth hath not seen him,neither known him.
Little children,let no man deceive you:he that doeth righteousness is righteous,even as he is righteous.
He that committeth sin is of the devil;for the devil sinneth from the beginning.For this purpose the Son of God was manifested,that he might destroy the works of the devil."
1 John 3:4-8
