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. God is love; and he that dwelleth in love dwelleth in God and God in him. (I John 4:15)
By confessing that Jesus is the son of God we are in Christ Jesus and in God. God is love, which makes Christ love also. Being in Christ Jesus allows the love of Christ and God to dwell in us.
God said like us make man in our image, according to our likeness. (Genesis 1:26) We were made in the image of God and we are in Christ Jesus. Plus the love of Christ and God dwells in us. I conclude that we are love. Therefore, we are to walk in love.
