500. If We Did Lack Free Choice in Spiritual Matters, Then in a Single Day Everyone on the Whole Planet Could Be Induced to Believe in the Lord; but in Fact This Cannot Happen, Because What We Do Not Accept through Our Free Choice Does Not Stay with Us
If free choice in spiritual matters had not been granted to us, then in a single day God could induce everyone on the planet to believe in him; but this is only taken as true when divine omnipotence is not well understood. People who do not understand divine omnipotence are able to reckon either that no divine design exists, or that God can act just as easily against his design as with it. But in fact, without the divine design no creation would have been possible. The first element of the divine design is that we are an image of God, so that we can be perfected in love and wisdom and therefore become more and more of an image [of him]. God continually works toward this within us, but if we had no free choice in spiritual matters that would allow us to turn ourselves toward God and forge a partnership with him, his work would be pointless, because his goal would be impossible to achieve.
There is a design from which and according to which the whole world and each and everything in it was created. And because all creation was brought about from that design and according to it, therefore God is called the divine design itself. Therefore it is the same whether you say "to act against the divine design" or "to act against God. " God could not act against his own divine design, since that would in fact be acting against himself. Therefore he leads every human being in a manner in keeping with his being that design. The wandering and the fallen he leads into that design; the resistant he leads toward it.
[2] If it would have been possible to create the human race without endowing it with free choice in spiritual matters, what then would have been easier for the omnipotent God than to induce everyone on the whole planet to believe in the Lord? Could he not have installed this faith in everyone, either directly or indirectly? He could have done so directly through his own absolute power and his constant, irresistible efforts to save us; or he could have done it indirectly through inflicting torment upon our consciences and devastating convulsions upon our bodies, and threatening us with death if we did not accept. He could have achieved the same result by opening hell to us and surrounding us with devils holding terrifying torches in their hands, or by calling up from hell dead people we once knew who now look like horrible specters. But to these arguments comes a response in the words of Abraham to the rich man in hell: "If they do not hear Moses and the prophets, they are not going to be persuaded even if someone were to rise from the dead" (Luke 16:31).
