“It is . . . no easier for sinners to accept God’s revelation in nature than to accept God’s revelation in Scripture. They are no more ready of themselves to do the one than to do the other. From the point of view of the sinner, theism is as objectionable as Christianity–theism that is worthy of the name is Christian theism. Christ said that no man can come to the Father but by him. No one can become a theist unless he becomes a Christian. Any god that is not the Father of our Lord Jesus Christ is not God but an idol.”
