There cannot be a higher standard for ethics than GOD, not because HE is all-powerful, but because HE is the source of goodness itself. Moral goodness is defined by the nature of GOD, and everything HE commands is in accordance with His perfect and righteous goodness. We must obey every Word of GOD because its flows from His character and His character is infinite and absolute moral perfection. GOD does not measure Himself against an abstract standard of goodness HE does not consult anything other than His own nature when HE issues commands and moral rules. His moral commands are not arbitrary and they could not be the than what they are since they are based on GOD's unchanging moral goodness. Since GOD's commands are found in Scripture, the Bible is our authority for ethics.
