Presbyterian philosopher and theologian, Cornelius Van Til (1895-1987), wrote in his book, A Christian Theory of Knowledge, that God is the final reference point for all that can be known:
If one does not make human knowledge wholly dependent upon the original self-knowledge and consequent revelation of God to man, then man will have to seek knowledge within himself as the final reference point.
Then he will seek to have an exhaustive understanding of reality. Then he will have to hold that if he cannot attain to such exhaustive understanding of reality, he has no true knowledge of anything at all. Either man must then know everything or he knows nothing.
The only way by which this dilemma can be indicated clearly is by making plain that the final reference point in predication is God as the self-sufficient One, (pg. 17).
