MGT attacks the holiness of God by teaching that He is holy only because He chooses to use His attributes in a loving way towards humans. In other words He can choose to be unholy in nature.
MGT says that God can and does make wrong choices and sin.
MGT teaches that God does not fulfill some of His own prophecies. They say that God changes His mind and is not immutable or that God is always in a state of change.
BIBLICAL EVANGELICAL VIEW: Only false prophecies, spoken by false prophets do not become reality. God does not change His mind according to His purposes. God never changes and one of the things that we can be confident in is the immutability of God. He cannot lie and He cannot be moved or change for His ways are pure, holy and righteous and need not be changed. (See Num.23:19; Deut. 18:18-22; 1 Sam.15:29; Hab.2:2-3; Mal.3:6; Tit.1:2; 2 Pet.3:9; Heb.6:18; Jam.1:17).
