I was recently listening to a sermon by Joshua Harris on 1 Corinthians 1:18-25. In this particular sermon Harris quotes H. Reinhold Neibuhr when he wrote:

"A God without wrath brought men without sin into a kingdom without judgment through the ministrations of a Christ without a cross."

You can listen to the entire sermon here. Also Justin Taylor has quoted this in the past as well--there is another great quote in that article as well.
