Faith in God is the Foundation of all Knowledge

It is a singular fact, and one which has not been often noticed, that faith in God is not only the foundation of all religion, but is also the foundation of all knowledge. If we do not believe in the credibility of those powers, which God has given us, and consequently if we do not believe in the goodness and truth of God as the author of those powers, we cannot believe in any thing. All knowledge, on this supposition, necessarily fails, because it is destitute of an adequate basis. But while we assert, that there can be no well established knowledge without faith in God, we can assert with still greater confidence, that there can be no religion without it. Religion, without faith in God as its basis, is an impossibility. At the same time in taking the position, that Faith is, and must be the foundation of religion, we ask as religious men, no more for religion, than philosophers ask, and are obliged to ask, for philosophy.
