"We do not believe, as some modern theologians would have it, that God's holiness only means his being God. Rather, it means that there are some things that conform to his nature and some things that do not. God's holiness, in other words, involves moral content....
"There is a great emphasis on love today. It is often viewed as having almost no direction, as being an unmotivated love -- love that is to be equal in all directions. But God's love is not contentless or directionless for the simple reason that God does not 'lack content'. He has a character."
