If you believe this (as many non-Reformed people do):
1) Jesus was sent by His Father to do the will of the Father, which was to save every single person of the human race.
2) That Jesus did not save every single person of the human race because the “free will” of many of those people denied His will from being fulfilled. Or that the power of their captivity to Satan was capable of frustrating the will of God.
Then:
What assurance do you have that Jesus will be able to overcome the “free will” of people when He returns to gather His people and reign in the New Jerusalem? Will His will be frustrated once again as it was the first time He came? Is there yet another power than can deny the will of God from being fulfilled?
Just asking.
