God - See Star Experience. God is Our Heavenly Father, but God is also has a Kingdom of God or collective of God and this is what many Christians don't understand about God. They don't realize that God is a collective of exalted beings who have become like God. There is only one kingdom or collective of god. That is why there is only one true god.
Jesus taught the truth about God very clearly in John Chapters 15-18 about becoming part of this collective of God to be at one with his Father as he and his Father want to be at one with us to become part of his collective because we are children of God.
The Fall was necessary. Downward yet forward in order to progress where God introduces in opposites for our growth and development and tutoring in this Second Estate (Mortal Probation). This is how God teaches his children. If no Fall, then no children or families or progress or growth. If no misery, then no happiness, Everything has an opposite. Opposites are necessary in order for us to exercise Our Agency, the freedom of choice. Without Opposites, which is what the Fall brought, we cannot choose between good and evil. If we cannot choose between good and evil then we cannot grow and develop.
