How can God pass salvation out to the whole human race?

Les explains that it is hard from the human element to comprehend that the Creator God took on flesh and was crucified, and that by that act of death and suffering and then being raised from the dead, God can pass salvation out to the whole human race. He maintains that every human being that has ever lived has already been pardoned by virtue of the work of the cross. Their pardon is accomplished. The only reason they are not going to receive it is because they will not appropriate it by faith. This is the same unbelief seen in Israel at Kadesh Barnea, who could not take God at His word, and it will be the sin of millions before the great white throne who cannot believe what God said concerning the work of the cross.
