In this was manifested the love of God toward us, because that God sent his only begotten Son into the world, that we might live through him.
Toward us, х en (G1722) heemin (G2254)] - 'in our case.'
Sent, х apestalken (G649)] - 'hath sent.' Into the world - therefore the Son existed before. Otherwise, too, He could not have been our life (1 John 4:9), our "propitiation" (1 John 4:10), our "Saviour" (1 John 4:14). It is the grand proof of God's love, His having sent His only-begotten Son that we might live through Him, the Life, who has redeemed our forfeited life: it is also the grand motive to our mutual love.
