The brilliant theologian and philosopher Hans Urs von Balthasar writes about God's involvement with man and man's involvement with God in the Old and the New Testaments. He shows 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 to enter into the realm of absolute and divine freedom, in which alone human freedom can be fully realized.
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 that preoccupies everyone. Atheistic philosophies are wholly taken up with this preoccupation. The Enlightenment was concerned with the freeing of reason from the "fetters 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 onward 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.
