For God so loved the world, that he gave his only begotten Son, that whosoever believes in him should not perish, but have everlasting life.
All Commentaries on John 3:16 Go To John 3
Hilary of Poitiers
AD 368
If it were only a creature given up for the sake of a creature, such a poor and insignificant loss were no great evidence of love. They must be precious things which prove our love, great things must evidence its greatness. God, in love to the world, gave His Son, not an adopted Son, but His own, even His Only Begotten. Here is proper Son ship, birth, truth: no creation, no adoption, no lie: hereis the test of love and charity, that God sent His own and only begotten Son to save the world.
