More insight from J. Gresham Machen in Christianity and Liberalism:
... liberalism has lost sight of the very center and core of the Christian teaching. In the Christian view of God as set forth in the Bible, there are many elements. But one attribute of God is absolutely fundamental in the Bible; one attribute is absolutely necessary in order to render intelligible all the rest. That attribute is the awful transcendence of God. From beginning to end the Bible is concerned to set forth the awful gulf that separates the creature from the Creator. It is true, indeed, that according to the Bible God is immanent in the world. Not a sparrow falls to the ground without Him. But he is immanent in the world not because He is identified with the world, but because He is the free Creator and Upholder of it. Between the creature and the Creator a great gulf is fixed.
... According to the Bible, man is a sinner under the just condemnation of God; according to modern liberalism, there is really no such thing as sin. At the very root of the modern liberal movement is the loss of the consciousness of sin.
