I mean where can you go in nature to show that God is omniscient?
Is it possible to conceive an absolute God without absolute knowledge?
What do you think of this statement by CVT? "It is the weakness of the Roman Catholic and the Arminian methods that they virtually identify objective validity with subjective acceptability to the natural man. Distinguishing carefully between these two, the Reformed apologist maintains that there is an absolutely valid argument for the existence of God and for the truth of Christian theism. He cannot do less without virtually admitting that God’s revelation to man is not clear. It is fatal to the Reformed apologist to admit that man has done justice to the objective evidence if he comes to any other conclusion than that of the truth of Christian theism.
As for the question whether the natural man will accept the truth of such an argument, we answer that he will if God pleases by his Spirit to take the scales from his eyes and the mask from his face. It is upon the power of the Holy Spirit that the Reformed preacher relies when he tells men that they are lost in sin and in need of a Savior.” The Defense of the Faith, p. 104.
