The Eternal Self-Existent God
"I am" is the most characteristic identifying name of God the Creator. All things in the cosmos, and the very universe itself, were created by Him, and the question "Who made God?" is inane. By definition, God is eternal and self-existent if there is a God at all. One can reject God if he chooses, believing that the universe itself is self-existent and that it somehow organized itself into its present degree of infinite complexity, but this belief flies in the face of the basic laws of science (causality, conservation, entropy). One can, on the other hand, choose to believe in the eternal, transcendent, omnipotent, omniscient, all-holy, self-existent God. He must do so by faith, of course, since complete understanding of such a Being is beyond the capacity of mortal minds. However, it is a reasonable faith, consistent with all known laws of science and with the innate witness of human reason and conscience. "I am" then becomes uniquely appropriate as the name of such a being, and this name is closely associated with the commonly used name of God in the Old Testament -- Yahweh (or Jehovah), normally translated in the King James Version as "LORD." Finally, it is significant that the Lord Jesus Christ identified Himself as this Being, when He said, "Before Abraham was, I am" (John 8:58).
The "I am" assertions by Jehovah in the Old Testament and the Lord Jesus in the New Testament are most remarkable in both their claims and their patterns of occurrence -- the latter centering around groups of seven. The number "seven" is always associated in the Bible with fullness or completion, ever since creation and the establishment of the seven-day week to commemorate God's completion of His work of creating all things.
