What does the Bible say about the only begotten Son?

The title 'only begotten Son' refers to the unique relationship between Jesus and God the Father. According to John 1:14, 'The Word was made flesh, and dwelt among us, and we beheld His glory, the glory as of the only begotten of the Father, full of grace and truth.' This emphasizes that Jesus is not just a representative of God but is truly God Himself, existing from eternity and embodying the fullness of God’s glory. His incarnation, without ceasing to be God, allows Him to relate to humanity while fully representing God's nature.
