wondering,
There is an interesting debate, now available in print form online, debate between Dr William Lane Craig (supporting free will) and Dr Ray Bradley, "
Can a Loving God Send People to Hell? The Craig-Bradley Debate."
Craig argues that ALL will not hear the Gospel:
"The Bible says that from the created order alone, all persons can know that a Creator God exists and that God has implanted His moral law in the hearts of all persons so that they are held morally accountable to God (Rom. 1.20; 2.14-15). The Bible promises salvation to anyone who responds affirmatively to this self-revelation of God (Rom. 2.7).
"Now this does not mean that they can be saved apart from Christ. Rather it means that the benefits of Christ's sacrifice can be applied to them without their conscious knowledge of Christ. They would be like people in the Old Testament before Jesus came who had no conscious knowledge of Christ but who were saved on the basis of his sacrifice through their response to the information that God had revealed to them. And, thus, salvation is truly available to all persons at all times. It all depends upon our free response."
I would add what Romans states: "Since what may be known about God
is plain to them, because God has made it
plain to them. For since the creation of the world God’s invisible qualities – his eternal power and divine nature – have been
clearly seen, being understood from what has been made, so that
people are without excuse" (Rom 1:19-20).
So, people do not need to hear the Gospel to have a reason to accept or reject Jesus. They need to deal with the revelation God has given them in creation and conscience (Rom 2:7) to face the Judge of all the earth.
