"Indeed, experience shows that it is only the mature Christian man who can begin to see the "size" of his Father. He may previously have thought that the comparison of the relationship between the toddler and his grown-up father with his own relationship toward God was rather an exaggeration of the gulf, in intelligence at least. But in his growing maturity he is likely to see that Christ, in His kindness of heart, has certainly not exaggerated the awe-inspiring disparity between man and God."
