On the cross, God judged our sins in the person of his son, and jesus endured the retributive comeback of our wrongdoing. Look at the cross, therefore, and you see what form God's judicial reaction to human sin will finally take. What form is that?
In a word, withdrawal and deprivation of good. On the cross jesus lost all the good that he had before: all spiritual well-being, all enjoyment of god and of created things, all ease and solace of friendship, were taken from him, and in their place was northing but loneliness, pain, a killing sense of human malice and callousness, and a horror of great spiritual darkness.
