Man has a very powerful will—so powerful that even God Himself does not break it. And by this [God] is actually showing that man is in the likeness of God. Without man’s will he could not make any progress on the way to goodness. So out of all the gifts that God grants the human being, we believe that freedom is one of the most important.
Agreed – assuming that “man” here is to be understood in a gender generic sense. I cannot accept the Calvinist position that men and women cannot resist the grace of God, because if God forced them to accept it he would be taking away their humanity and their image of God.
The problem is that the human will is so often opposed to the will of God. That, fundamentally, is why there is so much evil and suffering in the world. Don’t blame God, blame men and women who ignore his instructions and warnings.
And that is why in the end I disagree with what Rob Bell is supposed to have said, that hell will be empty. It won’t be because that is where some people will choose to go. Even if they were to have an eternity of chances to repent, many would not take them, as C.S. Lewis memorably put forward in The Great Divorce. It is not that God is a “vicious tormenter” who wants to send people to hell, but that he allows people to go to hell if that is what they want.
