No one has seen God at any time; the only begotten God who is in the bosom of the Father, He has explained Him.
– John 1:18 [emphasis added]
Jesus is “the only begotten God.” This phrase refers to His being raised from the dead.
Therefore, though we read about Him as a human being, His unique and seminal resurrection gives us reason to think of Him as God.
…we have known Christ according to the flesh, yet now we know Him in this way no longer.
– 2 Corinthians 5:16
