"But by the grace of God I AM what I AM..." 1 Cor. 15:10
"So that you also may know how I AM and what I AM..." Eph. 6:21
"Now I rejoice in my sufferings for your sake, and in my flesh I AM..." Col. 1:24
"Accordingly, though I AM..." Philemon 8
Not only is Paul claiming to be the Ex. 3 I AM, he is also not claiming merely to be one of three "Whos" but the "What"!
(For the sake of confusion, let it be known that this is a joke, much like many Christological interpretations. In none of these passages did Paul use ego eimi.)
