I am he
Isaiah 43:10
43:10 I am he. See notes on Exodus 3:14 and Isaiah 41:10. God here makes an absolute claim to all-encompassing Deity. The answer to the trivial question of the skeptic, “But who made God,” is that the one true God is the ultimate reality: there was no “god” before Him, and none after Him. The modern atheistic answer (“the universe made itself out of nothing by some quantum fluctuation of the primeval nothingness”) is credulous nonsense.
