Without free choice, love is impossible. God's ultimate plan is to perfect those who choose to be perfected. What is spiritual is eternal. All spiritual beings will live forever. Spiritual death, which came through man's sin, preceded the physical death of man.
All people now sin.
All enter life in a state of spiritual incapacitation. Life on earth has an eternal purpose. This life is roughly analogous to a school course with a final examination. Physical death has a good purpose. Suffering has a purpose.
