William Hendriksen, Galatians, Baker, 1995, p. 243-244.
The cross exposes man’s desperate state, his utter bankruptcy that made such suffering necessary. Accordingly, it reveals the folly of all human pride. It teaches man to say: “I never knew myself as a sinner, nor recognized Christ as my Savior until upon the cross I saw, My God, who died to meet the law that I had broken; then I saw, My sin, and then my Savior.” No one is ever able to see on that cross “the wonder of God’s glorious love” until he also sees “his own unworthiness,” and “pours contempt on all his pride.”
