The cross is about self-disclosure. God not only saves us on Golgotha he shows himself to us. N.T. Wright says this about the nature of God in connection with the cross. “God became on the cross what God always was. I may have it in me, in ability and desire, to climb Mount Everest; but until I actually go into training and do it it remains latent. You may have it in you to be a brilliant concert pianist; but until you get down to practice and performance, all that brilliance remains latent. God always was the God of love—generous, spontaneous, free and cheerful self-giving love; but until God, if we dare put it like this, gets down to practice and performance, that love at its deepest level remains latent. On the cross God performs the score composed before the foundation of the world. On the cross God at last scales the highest peaks. It isn’t just that the cross reveals God’s love in its most striking way. It reveals it because it enacts it. It becomes part of, indeed the most central part of, the personal history of God…And now, to all eternity, the cross remains at the heart of God, stands as the truest symbol of God, offers the most exact and precise exposition of God.”
