The givenness of Jesus Christ is bound up with the givenness of New Testament theology, which is … nothing less than the Father’s own witness through the Spirit to the Son. Surely there is no real Jesus save the Jesus of that theology. And New Testament theology … is essentially proclamation that Jesus Christ saves men from the bondage to false gods, false beliefs, false ways, false hopes, and false posturings before the Creator, into which all non-Christian religions and philosophies, impressive as they often are, are locked. New Testament proclamation diagnoses this whole kaleidoscope of falseness and falsehood as rooted in actual if unwitting suppression of general revelation, misdirection of man’s worshipping instincts, and ignorance or rejection of the gospel God has sent. Romans 1:18-3:20, to look no further, is decisive on that; and certainly Emil Brunner was correct when he wrote: “In all religion there is a recollection of the Divine Truth which has been lost; all religion, there is a longing after the divine light and the divine love; but in all religion also there yawns an abyss of demonic distortion of the Truth, and of man’s effort to escape from God.
