How do we know that Jesus is the only begotten Son of God?

The sermon highlights that Jesus is referred to as the only begotten Son in several scriptures, which underscores His unique and eternal relationship with God the Father. John 1:14 reveals that Jesus embodies the fullness of the Godhead, and passages like John 3:16 state that God gave His only begotten Son for humanity's salvation. This distinctive title signifies that there is no other being like Him, as He is not created but pre-exists eternally in a perfect relationship with the Father. This eternal begetting of the Son is outside of time, affirming His significance within the Trinity.
