When Abraham negotiated with God and asked Him to spare Sodom and Gomorrah even if there were only ten righteous people there, and God agreed, was He changing His mind, or revealing to Abraham that He already knew how debase these cities were from the very beginning? When God told Abraham to sacrifice Isaac did He change His mind at the last moment, and realize the error of His ways? Did he have a change of heart, or was His mercy already decided before Abraham took Isaac to Mount Moriah… even before the foundation of the earth?
