Commentary
Arguably the most recognized verse in the entire Bible, John 3:16 expresses the gospel in a single sentence. The word translated "so loved" is not an adverb of degree ("loved so much") but of manner ("loved in this way") — God's love is defined by what it does: it gives. The object is "the world" — not the righteous or the deserving, but a fallen creation in rebellion against its Creator. The gift is proportional to the love: not a blessing, not a prophet, but God's "one and only Son" (Greek: monogenes — uniquely born, one of a kind). Martin Luther called this verse "the gospel in miniature." To understand John 3:16 is to understand the heart of Christianity.
