εἶπεν αὐτοῖς Ἰησοῦς· ἀμὴν ἀμὴν λέγω ὑμῖν, πρὶν Ἀβραὰμ γενέσθαι ἐγὼ εἰμί.
Jesus said unto them, Verily, verily, I say unto you, Before Abraham was, I am.
Exodus 3:14 (LXX)
καὶ εἶπεν ὁ Θεὸς πρὸς Μωυσῆν ἐγώ εἰμι ὁ ὤν
And God said unto Moses, I Am That I Am
Ego eimi is a VERY unusual choice of words. Eimi means I am, Ego is unnecessary. So here we clearly see Christ using the name God used for Himself to to Moses. Thus it is clear that Christ calls himself God.
