Many acknowledge the three "wills" of God:
1. Decretive -- what God causes to happen
2. Moral -- what God desires to happen
3. Permissive -- what God allows to happen
The question at hand is under which one does a person's salvation fall.
We agree that it falls primarily under the Moral will.
Synergists argue that it falls secondarily under the Permissive will.
Monergists argue that it falls secondarily under the Decretive will.
1. God caused Christ to go to the cross.
2. God desires for mankind to be saved
3. God allows man to make the choice.
Looks like all three apply to mans salvation in different ways.
