You said God would not be just if the offer of salvation does not go to all. If this is so, God must be obligated in some way to all people. So I asked for scripture where it states that God is under such obligation.He understands what the gospel is teaching, but he understands it as foolishness. Man hasn't lost his faculties. They have simply been corrupted.
On the other hand, if Jesus paid for the sins of every single individual and God accepted payment for their sins, on what bases does God condemn them? He would be unjust for having accepted payment for their sins and then still demanding payment for them.
