The brilliant theologian and philosopher Balthasar writes about God's involvement with man, and man's involvement with God in the Old and the New Testaments, and how that interaction of the divine with the human reveals the meaning of true freedom that man is always hungering for but often strives after in wrong and dangerous ways. He shows that God's free revelation of himself in Christ is an invitation into the realm of absolute and divine freedom, in which alone human freedom can be fully realized.
Balthasar demonstrates that through God's becoming man in Jesus Christ, which is an example to all of true fulfillment, there is a break-through and entry into the sphere of precisely that kind of freedom which is so feverishly sought after by modern man but which, without the revelation of God, he can never otherwise find.
From the true Christian there radiates the kind of freedom that is constantly being sought after by the non-Christian. In modern times, the freedom of man is a theme which preoccupies everyone. Atheistic philosophies are wholly taken up with this preoccupation. The Enlightenment was concerned with the freeing of reason from the "letters of faith". Marx wrote about freeing man economically, and Freud wrote of freeing man from the bondage of a past as yet unmastered.
As opposed to those whose search for freedom urges them onwards into a barren void, the Christian stands as the messenger of freedom accomplished and a freedom attainable by all. A true freedom of the sons and daughters of God.
"Just as Love Alone Is Credible captures the essence of the seven-volume The Glory of the Lord, so does Engagement with God explain his five-volume Theo-Drama. But here he does more: by setting his account of the drama of Christian discipleship against the anti-Christian ideologies of the 1960s he brings his theology to bear on the highest cost of discipleship-martyrdom-by seeing the martyr as the mirror of God's own involvement in the human race through his own martyred Son. One can hardly read a more sober, and yet exhilarating, account of what it means to live committed to God's own commitment to the world."--(Edward T. Oakes, S.
