And also the God of Abraham IS Jesus Himself.
JESUS -- AS THE ANGEL OF THE LORD -- SAID THIS TO MOSES
And the Angel of the LORD appeared unto him [Moses] in a flame of fire out of the midst of a bush: and he looked, and, behold, the bush burned with fire, and the bush was not consumed... And God [Jesus] said moreover unto Moses, Thus shalt thou say unto the children of Israel, The LORD God of your fathers, the God of Abraham, the God of Isaac, and the God of Jacob, hath sent me unto you: this is my name for ever, and this is my memorial unto all generations. (Exodus 3:2,15)
