As far as the argument goes, this is true. However, the claim that Jesus’ words in John 8:58 (and the other passages) should be connected to Exodus 3:14 does not exist in a vacuum. There is a line of argumentation, a very solid one, that leads us from John 8 back through Isaiah to Exodus 3. We need to trace that path before we can make the statement that Jesus is, in fact, using a name of deity of himself in John’s gospel.
