John says that we know that they are of the antichrist because they went out from us. There is nothing that says to hate the unbeliever. Love is not confined to the body of Christ.
Love is only possible within Christ, because God was in Christ reconcilling the world back to Him, for 'God is love'.
If you say that love exists outside His body, you do not understand love, i.e. "Hereby percieve we the love of God, because he laid down his life for us (Christians); and we ought to lay down our live for the brethren
adelphos, do you know what brethren means? The Greek means 'connective particle' from
delphus which means womb, lit. relation from the womb - brethren.
In no way does John or any other Apostle speak of loving the enemies of Christ, antiChrists, love for antiChrists would be a sin against the holy Spirit.
Now where does love come from? John says the source of love is God, and you do not know love unless you know God, the love of God is manifest toward Christians, it is a gift to be shared amongst brethren;
"Whosoever believeth that Jesus is the Christ IS BORN OF GOD" Let me repeat that "WHOSOEVER BELIEVETH THAT JESUS IS THE CHRIST IS BORN (
gennao) OF GOD" That means literally concieved by God, born, begat, brought forth, procreate, bear, born, GOD brought ye forth, He delivered you, He begat you! A Christian is born of God, which make other Christians - 'brethren', related by birth to God!
Now Jesus says there can be NO division in the body of Christ, John says he that loveth God is born of God, he that does not have the Son, is not of God, he does not have the Father, and there is no love in him, neither truth, if there was he would recieve the gospel of salvation, for he knoweth and loveth God, and he hears God and follows, the sheep know the voice of the shepherd, and the Great Shepherd knows His sheep that belong to Him, and He finds them and loses none.
"
Whosoever shall CONFESS THAT JESUS IS THE SON OF GOD, God dwelleth in him, and he in God. And we have known and believed the love that God hath to us (brethren), God is love, and he that dwelleth in love dwelleth in God, and God in him." 1. John 4:16
No love exists outside the body of the Son of God, love of God dwelleth in the heart of the believer, a non-believer hath not the love of God, love only exists between the connective parts of His body, God extends His love to those that are born of Him.
