John 8:58
Jesus said unto them, Before Abraham was, I am — Jesus's response is the climactic revelation of chapter 8. 'Before Abraham was' (prin Abraham geneesthai) means before Abraham came to exist. 'I am' (egō eimi) is the divine name, the revelation to Moses at the burning bush (Exodus 3:14). Jesus claims an existence prior to Abraham, grounded in the divine being itself. This is the fullest assertion of Jesus's divinity in John: he is not a created being (even the first-created); he exists in the eternal present of God. The statement moves from temporal sequence (before... was) to the timeless divine being (I am).
